Hello, everyone, and welcome to this presentation
00:11
about setting up Revit for AEC project.
00:14
Thank you for joining.
00:16
My name is Daniel.
00:17
I'm working as a designated support specialist in Autodesk
00:21
and I'll be presenting today.
00:23
By the end of today's session, you'll
00:25
learn about what you need to do before starting
00:29
the project in Revit.
00:31
We will talk about coordinate system,
00:34
we will see what take into account in the model strategy,
00:39
how to know the best of the model maintenance,
00:43
how to work with different links in Revit.
00:47
And we will need some good practice about performance.
00:52
Before starting, I want to share the safe harbor statement.
00:56
Essentially, it says the product and service and features are
01:01
subject to change and purchasing decisions should not be made
01:04
based on this presentation.
01:06
And let's move to the first section,
01:08
what these recommend doing before to start the project.
01:12
In general, companies working with Revit
01:14
invest time and effort in developing templates
01:18
according to their own standards because they
01:21
know the template help to maintain
01:23
quality and consistency across everyone within a field.
01:28
They also save users a lot of time
01:31
by setting up the necessary standards in advance
01:35
so people don't have to start everything from scratch.
01:39
This is especially important for some discipline,
01:43
the structural design and they MEP discipline
01:46
because they have to accomplish in general very
01:49
complex calculation.
01:50
And there are very specific settings
01:52
that they are only specific to this discipline.
01:56
I'm thinking, for example, about reinforcement parameter,
02:00
this is only important for structural engineers
02:03
in general.
02:04
MEP or architects don't need to have
02:07
all these setting correctly set up in the template.
02:11
Is the same with other setting for MEP
02:14
or structural engineers.
02:16
So where can you find the various project templates
02:20
in Revit?
02:21
When Revit is installed, default Revit templates
02:26
generate Autodesk has been saved in the following path.
02:31
So you have in C, program data, then from the Autodesk, Revit
02:36
and the version of Revit and then templates.
02:40
Please note that the file extension for Revit templates
02:43
is not rvt coming from the right [INAUDIBLE],,
02:46
but this rte from Revit template.
02:49
There is a different one for Revit
02:50
families and Revit family templates.
02:54
As we said before, you can create new project templates
02:57
and save them in the same location or a different one.
03:01
In Revit, through file, option and file location,
03:05
you can specify the default location of the one Revit
03:09
will show up when creating a new project.
03:12
To facilitate the selection of the template,
03:14
when do you want to create a new project?
03:16
If you do not see in there the specific template
03:20
you want to bring it to your new project,
03:24
then you can always browse for it.
03:26
So you see it here.
03:30
By Browse, you can select the template
03:32
that it's maybe [INAUDIBLE] and all that.
03:35
Finally, all these setting definition path
03:38
and other variables can be managed through a simple txt
03:41
file.
03:42
It's the Revit.ini file.
03:44
As I say, it's a simple txt file and very
03:48
useful to distribute across the whole organization
03:51
and make sure that all user get the right path to the company
03:55
templates and to other variables that you want to standardize
03:60
What could be included in project templates?
04:03
Anything included in project template
04:05
is subject to customization.
04:08
We can even divide in 3D groups or you can include it
04:12
in project templates.
04:13
We are grouping by visibility, content and setting.
04:17
In this slide and the following one,
04:19
you see a list of the main topics included in each group.
04:24
In relation with visibility, you can include viewport types,
04:29
you can bring views, already defined views, schedules,
04:33
sheets and legends.
04:35
You can include view types, you can prepare the browser
04:40
organanization as you desire.
04:43
You can include filter.
04:44
And what is very important, you can put view templates or color
04:49
schemes.
04:49
We will talk about view templates.
04:52
About content, you can include the naming standard
04:56
you are used to work in the company,
04:60
you can bring annotation family, title blocks,
05:04
any kind of family outlook, loadable
05:05
and system family can be already included in the templates.
05:09
All type of parameter, project parameters, shared parameter
05:13
and global parameter can be included as well.
05:16
And you can prepare some placeholder links
05:18
that you will lead that change by the right model.
05:23
Related to Settings, we can include many points.
05:27
Here, a list of the main ones.
05:30
So we can bring material libraries, object style.
05:34
We can define the settings to export the DWG.
05:39
We can have the line of style, and you see here
05:43
in the screenshot.
05:44
Line wave, line pattern, we also include it,
05:48
hatch pattern as well, MEP setting
05:51
and the structural settings, revisions,
05:54
the units of the project.
05:57
You can predefine worksets and phases.
06:02
There are other templates very important to take into account
06:05
to assure a standardization and maintain
06:07
the quality and consistency of your project.
06:09
These are the view templates we talk about before.
06:12
All these are view template.
06:14
So a view template is a collection of view properties.
06:18
As the scale, the detail level, some visibility
06:21
settings and so on.
06:24
View templates are used to a standardized project views.
06:28
You can in View Templates, you can create templates
06:31
from Current View, then you can apply the template
06:35
to the current view or to a different one.
06:38
And you can manage the view templates
06:41
and change the visibility settings.
06:44
View template as best practice, prepare them
06:48
before starting a project.
06:50
Even if you will define and [INAUDIBLE] step by
06:53
step building the project life.
06:56
Many of them view templates have been improved
06:60
during the project life of our Revit project,
07:03
therefore we decide to recover them from different projects
07:06
to the current one.
07:08
There is a very useful tool allowing you to transfer them
07:11
between two Revit client or between a family and a project.
07:16
It is called the transfer project standard tool.
07:20
Actually, there are multiple combinations
07:21
you can transfer projects standard between doing
07:24
Revit project, Revit template or Revit families.
07:28
Any combination that you want between all these type.
07:31
So let's see how to transfer project standard.
07:34
To transfer projects standard, first of all,
07:36
we need to open in the same Revit session
07:39
both of the files.
07:41
In the target file, you have to be active in the target file
07:45
and then go to Manage tab, Settings panel and Transfer
07:48
Project Standards.
07:51
Select the source project for Copy from in case
07:54
that you have different files open there.
07:58
And then to select the desired project standard
08:01
that you want to bring, there are different categories
08:04
that you can select.
08:06
We will see in the next slide, which one and you will bring
08:09
into your current project or the families
08:12
that they are included in this category.
08:15
If there are duplicate types, a duplicate type dialogue
08:19
will be displayed.
08:20
You will have the possibility to select the option
08:23
to override the family that you have in your current project
08:27
to bring only the one that they are new
08:30
or to cancel the whole operation.
08:33
So what can we include when transferring project standards.
08:37
There is a long list of categories
08:39
we can recover from one project to another.
08:42
As you can see in this slide that actually is not
08:44
showing all of them but you can get
08:47
an overview of the different topic you can include.
08:50
In the right, you can see a screenshot
08:51
of the different categories that you can get
08:54
and you can select all of them, you
08:56
can just select the one that you decide to transfer
08:59
from one project to another.
09:02
When transferring project standards,
09:04
there are a few good practice to take into account.
09:08
In the out of the box solution, there
09:10
are some limitations to transfer a specific family or type.
09:14
It is just not possible to select which type
09:16
or which family from specific categories
09:19
you want to transfer.
09:20
It is only possible to select the whole category.
09:23
If the idea is to get back in your project specific families,
09:26
you always have the possibility to copy paste
09:30
or to save in your window folder and log it again
09:34
in your project.
09:35
Keep in mind that you can also use Dynamo to load
09:38
multiple families at once.
09:40
It can be very useful to automate the process
09:43
at the beginning of the project or when
09:46
changing to a new phase.
09:48
It is convenient to transfer system families that
09:51
rely in other system families at once
09:54
because you will make sure that their relationship is correctly
09:58
maintained.
09:59
We can repeat the same tip for view template and filter.
10:03
They should be transferred together not
10:04
to lose the relationship of the filter that are included
10:08
in each specific view template.
10:10
Be careful, if the target project contains already viewed
10:14
templates and filter with the same name, in that case,
10:18
you might want to rename or delete them before.
10:22
There are some items in Revit not subject to be transferred
10:26
between projects.
10:27
These are elevation or section types and the visibility
10:30
setting for Revit links.
10:33
As you might be aware, it is not possible to store system family
10:36
out of the Revit project.
10:39
System family rely are safe within the session of the Revit
10:43
project.
10:44
It is a good practice then to save
10:46
system family as wall, floor, ceilings, stairs, pipes
10:50
or ducts, et cetera of the system family
10:53
within a Revit project.
10:54
And every time you need them, get the family type
10:58
back from this project by copy pasting it.
11:01
Consider to have then in that case
11:04
a specific project for each specific category.
11:07
For example or by discipline you can
11:10
get one project for architectural system
11:14
family, one project for MEP system family
11:17
or you can do it by categories.
11:20
So let's surely talk about the coordinate system.
11:23
Actually, coordinate system represent
11:26
by themself a big topic.
11:27
A whole presentation would be needed to address and explain
11:31
it properly.
11:32
However, I want to include in this presentation
11:35
a short statement on this because it's really
11:38
important that when sending out your project,
11:41
you position correctly your project.
11:44
In where you have the possibility
11:45
to specify the geographic location using
11:48
the address or the near city or the latitude and longitude.
11:53
This is very helpful for solar studies weather analyse,
11:57
et cetera.
11:59
But please, know this is not georeferencing your model.
12:03
Usually, we need to do georeference our new model
12:06
and therefore we need to define the survey
12:08
point to match with a known point in the world.
12:11
We can use survey coordinates from the civil engineer
12:14
for example or we can determine the coordinates of a known
12:17
location, such as the intersection of the property
12:21
line or a geodetic survey marker.
12:24
Very probably, it will be needed to protect the project North,
12:29
to define it correctly that epsilon axis of the survey
12:33
point.
12:33
Or maybe is the countrary and you
12:36
can rotate the project North before starting
12:38
to model anything.
12:40
The project based point will be automatically updated
12:43
with the right coordinate as soon as you have correctly
12:46
defined the survey point.
12:47
However, it will be convenient that you define properly
12:52
the project based point in a specific location
12:54
in your project, maybe the corner of the project
12:57
to establish a reference for the [INAUDIBLE]..
13:01
Once we have accomplished that, we
13:03
can start importing or linking other models or other CAD files
13:08
And we can use the appropriate positioning option.
13:11
So maybe you want to link auto by share coordinates, Auto
13:17
origin to origin or automatically
13:20
project based point to project based point.
13:22
If we need to coordinate the location of multiple building
13:26
or different parts of the same building.
13:28
It is very common to use them, the shared coordinates.
13:31
All the shared coordinates, why we will use?
13:34
Shared coordinate are used for remembering
13:36
the multiple position of different interlinked files.
13:40
Those interlinked files can be ultra [INAUDIBLE] file
13:43
or it can be a combination from Revit DWGs or the [INAUDIBLE]
13:47
files.
13:48
As I say, and that is a very short overview
13:51
of the possibility to position and to your reference
13:54
[INAUDIBLE] models.
13:56
Let's move then now to the next section about model strategy.
14:00
What is LOD?
14:02
LOD stands for Level Of Development.
14:05
Data specification combines how an element geometry is defined.
14:10
They associate information attached
14:12
to it and the evolution through the different phases
14:16
of the project.
14:17
So actually, three topics.
14:19
Remember, geometry, information, associate
14:23
to the element and the evelotion through the phase,
14:26
different phases.
14:27
LOD start at level 100, at the very beginning of the project
14:32
doing the conceptual design phase
14:34
and reaches 500 when it's in operational phase.
14:40
During different LOD steps, the geometry representation
14:44
of the element is getting more and more accurate
14:48
but at the same time we are adding
14:49
more and more information to that specific element.
14:53
On the table on the right, you can
14:55
see an example of the proposed geometry
14:59
level that is associate to each specific level of development.
15:03
And you can see also different information
15:06
that is recommended to have on each specific LOD.
15:11
In reality there is not a clear maximum size of the model.
15:14
Actually, performance is not only dependent on the size
15:20
but is really dependent on the complexity of the model, which
15:24
is much more difficult to identify that the size
15:26
of [INAUDIBLE].
15:27
The experience will let you know and to understand
15:29
ideal the size of the project depending on the use case
15:34
you are handling.
15:35
Sometimes we hear 400 megawatt is something ideal maximum
15:39
size, but again it does not apply to every model.
15:44
Very often, we will need to break up
15:47
then the project in different model
15:49
to avoid working with a very heavy file.
15:53
For example, in architecture and that's
15:55
the screenshot that you can see there,
15:57
a good practice is to break up the model in different part
16:03
like this one.
16:05
In the bottom we have the basement
16:07
then we have the commercial part, the office level
16:13
and the residential level.
16:15
That will be a good practice to divide architectural model
16:19
for example.
16:20
Actually, we can also have the facade in a different model
16:24
and multiple combination.
16:26
Another good practice when a splitting model
16:29
will be to split it by different disciplines model.
16:32
You will have one model for architecture,
16:34
one model for MEP, one model for a structure and so on.
16:38
Another solution is to prepare and define
16:40
many modeling zones defined by your scope box for example
16:44
and then start splitting from there.
16:46
So typically, in architecture, we are split by external shell,
16:52
vertical communication stair, an elevation shaft interior spaces
16:58
for example or zone in as we saw before for residential,
17:02
commercial, and office.
17:06
In a structural design is not the same,
17:09
we often split by dilatation or construction joints.
17:12
In MEP is, again, different and we are split by system
17:17
independently if the system is 30 meters high.
17:21
It is important, of course, in MEP
17:23
to have closed system in the same model.
17:26
As you can imagine, the process is not
17:29
easy to achieve but you will find
17:32
that this a big improvement in the performance
17:36
once you do the correct split of the model.
17:40
We've just seen how to split models.
17:42
Views, sheets, and schedules are also
17:46
impacting the performance of the Revit file.
17:49
You can think as well to minimize splitting the model
17:52
and creating a container file to link your model
17:56
and create there all the views, sheets, and schedule.
18:01
This is particularly useful for architects
18:04
that very often need to deliver many, many views
18:07
from the same floorplan.
18:08
So let's have a look to this diagram.
18:11
At the top, we start our project by choosing the correct project
18:15
template as we were saying at the beginning
18:17
of the presentation.
18:18
Then once we have our project open and safe,
18:22
let's call project model, we define on this file
18:27
just the coordinate system properly.
18:30
So we define the survey point and we
18:33
positioned the project base point where we really need it.
18:38
But we do not model anything complete one.
18:40
We will keep this file, let's call, I clean
18:45
file that we can use as many times as we want.
18:48
So we will save this file one as model file.
18:53
So the model project file is this one
18:56
and we will save again this one as a layout.
19:02
We link the model into the layout.
19:05
So we will use the model 90% of our time to model everything
19:12
from a project and the layout to create views, to create sheet,
19:18
and to create a schedule if needed.
19:21
Let's see a bit more in detail.
19:22
What should these model file contain?
19:26
It contains all valid model elements.
19:30
We should create some views as working in progress views
19:33
but we should minimize the number of views, sheets,
19:36
and schedules.
19:37
We minimize as well the number of annotation.
19:40
I suggest we prepare one view by level, one section, and one
19:45
elevation that usually we need it also lay layout.
19:49
And we prepare one for each specific ready to be printed.
19:54
They can be shown in the layout later on us by DMV
19:58
we will see later on how we link it there in that the case.
20:02
So actually because you are working in the model,
20:07
then most of your time it's good to have
20:09
from each specific level, elevation and section
20:13
you are usually printing one Revit view but not
20:19
What should be then included in the layout?
20:21
We have linking the model Revit file into the layout.
20:25
You can also consider having one layout for the normal plans
20:30
and one for details.
20:31
We can call it layout plans and lay out details.
20:34
But in general, I would say minimize
20:36
the number of layout file because it
20:38
helps you to avoid numbering issues having
20:42
a better control of the naming and numbering of the sheets.
20:46
Create all views that you needed to be
20:49
printed on these layout file.
20:52
If needed, you can duplicate views
20:54
and duplicate that's dependent and crop to fit in the sheet.
20:59
For other needs, consider to create
21:01
views for different concept as for material, ceiling
21:06
plans, concept of door and so on, all these does not need
21:11
to be created in the model.
21:13
So we needed in layout file assign view template
21:17
to control the visibility.
21:19
You can override in visibility graphic by host view,
21:24
by linked view and by custom.
21:26
So it means by default when you are
21:29
linking the model in the layout, views
21:32
will appear s host to you.
21:35
It means that the view template is
21:38
controlled by the layout file.
21:41
If you want for a specific view to be control
21:45
the visibility setting from the model file,
21:49
then you have to specify by link view
21:52
and you just select the view from the model file
21:56
that you want to represent in the layout file.
21:59
Custom will be a mix solution where
22:01
you will choose the view from the model file
22:04
that you want to bring in the layout.
22:07
But still, you can customize and do some changes in the layout.
22:12
If you are creating a schedules or quantities take off
22:16
in the layout, remember that you should include links.
22:20
If not, it will be empty of course.
22:22
Annotation is recommended to do it in the layout
22:25
because then the model file will be more performant
22:29
and maybe you can consider to use a scope
22:32
box to control the crop region of multiple views.
22:36
And like this one, you are placing different floor plans
22:40
in the layout in the sheet.
22:41
They are all sitting in the same place
22:43
and they are not jumping out.
22:47
So here we find a very schematic overview of both Revit file.
22:53
On the left, you can see what we call before the model Revit
22:58
and on the right, the layout.
22:60
As you can see on the Revit, there
23:02
is one floor plan by level.
23:04
Actually, we create one floor plan by level
23:07
and there are no sheets.
23:09
In sheets, it's empty.
23:12
But in the layout Revit file, we have duplicate [INAUDIBLE]
23:18
each specific level because they are not fitting in the sheet.
23:23
So actually we have four different views
23:27
for each specific level.
23:29
And moreover, we are having some views
23:32
that they are showing the concept, as we say,
23:36
circulation concept, door concept, floor finish
23:39
concept and so on.
23:41
So we are creating use floor plans
23:45
that they are not existing in the model.
23:48
We will create the schedules and quantity as well
23:51
and we will do all the sheet, we will create it here
23:55
in the layout.
23:57
[INAUDIBLE] existing here.
23:58
As you can imagine, all these is increasing.
24:01
If we will combine both of model and view sheets
24:06
and quantity in the same file, the size
24:09
will be sometimes not easy to handle.
24:13
So therefore, it will be a solution to a split it
24:16
in model and layout file.
24:19
So now, let's move to a different topic, worksharing.
24:22
What is worksharing?
24:24
Work sharing is a design method that
24:26
allows multiple team members to work on the same project
24:30
model at the same time.
24:32
On work sharing project, team member
24:34
are assigned to a specific functional area to work
24:37
and that is managed by the worksets.
24:40
Non-worksharing private project [INAUDIBLE] or city neighbor,
24:44
you start using worksharing in the project
24:48
as soon as you create the first worksets.
24:52
A workset is a collection of elements in a project.
24:56
They only exist in workshared projects as we said before.
24:60
Revit use the technology of workset
25:03
as a mechanism to enable multiple user to collaborate
25:07
on one central model.
25:09
And they are taking the ownership of the element
25:12
when they are attached to one of these worksets.
25:16
So now that we define what is a workset,
25:19
you can create workset based on different functional areas
25:22
such as the following, so for example
25:24
for architectural and structural engineers,
25:26
often, we create workset for interior
25:29
or exterior for the site or the facade, our furniture
25:34
and so on or in MEP, we often create a workset for HVAC,
25:41
workset for electric car, workset for plumbing.
25:44
And if the project is very big and complex,
25:47
you can subdivide as many walls of that you want.
25:51
Maybe you want to create plumbing
25:53
for a specific system as cold water in one water,
26:00
hot water in another, and so on.
26:03
That is an important distinction between working
26:06
with ownership of a workset and borrowing from a workset.
26:10
In fact, when you make a workset editable in Revit,
26:14
you are taking exclusive ownership of all the objects
26:19
that they belong to these specific workset.
26:22
Only one user can at one point be the owner of one workset.
26:27
Two people cannot be owner of the same workset.
26:30
But however, all team member, even if somebody
26:33
is the owner of the specific workset,
26:35
all team member are able to see in the project all the workset
26:40
even if they are not owned by a different team member.
26:43
But there is also the possibility
26:45
that you are not taking ownership of a specific workset
26:48
but you are borrowing a specific workset.
26:53
First option is in general a more stricter and less risky
26:59
but the second one gives you more flexibility.
27:02
Of course you can use a combination of them
27:05
and take the ownership for a specific workset
27:07
and let the others to use their borrowing option.
27:11
So with that said, let's move to a different topic
27:14
about model maintenance.
27:16
There are a few regular work to do to keep a healthy
27:20
and perform a model.
27:22
So if you are familiar with AutoCAD, the audit command,
27:25
you can understand how audit can help you to keep up performing
27:29
model in Revit as well.
27:31
The audit function scans, detect and if it's possible,
27:37
it will fix corrupt element in the model.
27:40
But keep in mind that it does not
27:42
provide you a feedback of which element has been fixed.
27:46
You have the opportunity to audit model
27:49
when opening a Revit project.
27:51
If you want to audit, you have to close it and open it again.
27:54
For workshare model, make sure that all user close their work
27:59
and they do not open again.
28:01
They'll all save local file.
28:04
If I create new one from central, if they do not do so,
28:08
you'll get back the fix error in your central file.
28:12
Auditing a model can be time consuming.
28:14
If the model is healthy it should not be very significant,
28:18
but still it can be time consuming.
28:21
So therefore we recommend to do it weekly or even daily
28:25
because you make sure that it will not
28:27
take too much time the next time that you will audit it.
28:33
And be aware that you can audit Revit project files
28:36
but you can also audit Revit families
28:39
and audit Revit templates.
28:42
Purge is also a known command in AutoCAD.
28:45
You have it as well in Revit.
28:47
It remove unused element as views, families, groups, et
28:52
cetera from the project to improve the performance
28:55
and reduce the file size.
28:57
But before purging, it is recommended
28:60
that you create a backup project file in case you
29:02
want to get back some elements that were included in the model
29:07
library but they were not in use.
29:09
In general, it's recommend not to purge all
29:12
that you find in your project but to Check None at first
29:16
and select exactly what you decide to purge.
29:19
These actually should be done by somebody
29:23
with some responsibility in the project.
29:26
Keep in mind then that when you're
29:28
working with workshared project, all workshared should
29:32
be open to use these tools.
29:34
And models that contain elements load
29:38
for a future phase in the project
29:40
as it can be that you have views,
29:42
some families, materials, any content that you want
29:46
to use in a future has been load previously,
29:49
will be also purged if you do not control it.
29:52
So be careful to purge something you need later.
29:55
Therefore, it's recommended that is done by the BIM
29:59
manager or the BIM coordinator.
30:01
You can also compact central models when synchronizing.
30:05
What is compacting central models achieving?
30:09
This helps reduce file size when saving workshare project.
30:13
So it's just value for workshared project.
30:15
The process of compacting rewrite the entire file,
30:20
it remove part that they are no longer needed
30:24
and therefore it will save some space.
30:26
Actually what this is doing is it's readjusting the database
30:30
and readjusting how the information is
30:35
stored in a more efficient way.
30:38
It is recommended to periodically select
30:41
the option of compact central model
30:44
when synchronizing to central.
30:46
In general, it's not significant time consuming
30:49
but the process can sometimes take longer
30:53
than normal synchronize takes.
30:56
So it's recommended to do if you can interrupt
31:00
your workflow for a bit longer.
31:04
The benefit of a compacting central model
31:08
is just as we say, for version model,
31:12
is not affecting the local file from the central model,
31:18
that you extract from the central model.
31:20
And this is not possible to do it for normal none
31:24
workshare Revit project.
31:27
So therefore because it's not extended to local files,
31:31
it is recommend that you are creating new local file
31:35
at the beginning of your work day
31:36
and not to open your old local file
31:40
because you will lose the power of compacting a central model.
31:46
It is very usual for Revit model get very different warning
31:50
types.
31:51
So when working on a Revit project,
31:53
you can review a list of warning methods
31:56
to use and to find issues that might
31:59
require review and resolution.
32:02
Unlike error methods, warning methods
32:05
do not prohibit the current action.
32:09
You do not realize when a warning occurred.
32:12
You are modeling and modeling and suddenly you
32:14
realize that you have a couple of hundreds warning,
32:18
but the warning they just informed you
32:20
that a situation might not be your intention
32:24
and you can then decide if you want
32:26
to correct or to ignore it.
32:29
So it's recommend that you review
32:31
and you correct the warnings regularly not
32:35
to come at the end of your project
32:36
without enough warnings.
32:38
And you should know that you should prioritize the warning
32:41
that they are involved in geometry and calculation,
32:44
how they can affect your performance of your model
32:48
or the quality of the model.
32:50
So in general, there are warning that they do not
32:53
affect performance and there are warning they do affect.
32:57
But you should concentrate resolving the one
33:00
that they are giving some inaccuracies in the drawings
33:04
or the one that they are about duplicate element or clash
33:08
detection elements because all these error or warnings
33:12
actually have an effect of the cost estimation of the quantity
33:18
estimation, the quantity they got,
33:20
and the clash detection of your project.
33:23
So warnings can be exported in a HTML file.
33:29
This file will include the error message
33:32
and the ID of the element that they are impacting.
33:36
So we recommend that you use these ID
33:38
that you find on the HTML to find the element in Revit
33:43
and then check if you should repair or not
33:45
and understand where the problem is happening.
33:49
And finally for this section, is also
33:51
recommend to manually review your model.
33:54
There is a way to have automate the process.
33:57
You can use working in process schedules in Revit
34:00
to review the data and check if the parameter are populated
34:05
correctly.
34:06
So for example, you can use the grouping
34:09
and the conditional formatting in schedule
34:12
to identify elements with parameters
34:14
that are usually out of range.
34:17
It is a good practice to prepare some work in progress schedule
34:21
to continue monitoring the quality of the model.
34:24
So for example, you see here on this image,
34:27
there is a scheduled for walls that we are controlling
34:32
the height of the wall.
34:34
So we know that this specific family type of wall,
34:38
there is [INAUDIBLE] basic wall interior
34:41
is usually room height.
34:43
So if suddenly it's not going to the--
34:47
it's just 1 meter or 1 meter
34:53
actually it's jump out in a different line
34:57
and you identify that.
34:58
It might be an currency.
35:00
So that's a way to check if the model is correct or not.
35:05
You can do it also to see the high position of the door
35:08
or of the window.
35:10
So if this specific family window are not
35:15
sitting 80 centimeter from the floor,
35:17
then it jumps out of the list and you can easily look for it.
35:23
So let's jump now to the next section
35:25
about how the work with links.
35:28
In Revit, we can link and we can as well
35:32
import different file format.
35:34
So we can link Revit models, we can link or open IFCs,
35:40
we can link or import CAD format as dwg, dxf, dgn, sat, SketchUp
35:49
or 3dn.
35:50
But actually, there are other type format
35:53
that we can bring as topographies from dwg
35:57
as well or from pixable, we can link
36:00
point cloud, coordination model from Naviswork, Nvidia NVS, VC.
36:06
We can link or import PDF and images.
36:10
Let's talk about Revit models link in driving model.
36:14
We are linking driving model into Revit model
36:17
for different purposes.
36:18
So usually we are going for putting together
36:22
different buildings such as a campus, where
36:25
we link different building into one file collecting
36:29
all the different building together.
36:31
We are doing as well to put together a different part
36:34
of a same large building.
36:36
So it can be that the facade is one Revit model,
36:42
the interior is a different one.
36:44
Maybe the side is another model and so on.
36:48
We are doing also to coordinate disciplines are
36:51
as the one we see in the image.
36:52
So on the top right, we have the architectural model
36:57
and on the bottom right, we have the structural model.
37:00
And finally, we can do it as well
37:03
from the workflow we saw before to bring the model
37:07
into our layout model.
37:08
So we do all the modeling in the model
37:13
and we define and we link this one in the layout
37:17
that we define.
37:19
Links model are listed in the Revit links
37:23
branch of the project browser.
37:25
So here, Revit automatically update the link
37:29
when you open the project.
37:31
That's why you can always have these links
37:34
if you go to Manage, Manage Links
37:36
and then just reload them [INAUDIBLE],,
37:39
if you want to reload the link model
37:41
during your private session.
37:43
Be aware that you should set up correctly the link reference
37:47
type.
37:48
You have the possibility to choose
37:50
between overlay and attachment.
37:52
Overlay does not load the link model
37:56
when its host is link into another model.
37:59
And by default, this is the setting
38:01
you get when you link the model.
38:03
So that would be the schema represented in this game.
38:08
So you will link the project A in the project B as overlap
38:12
and then you link the project B in project C.
38:15
In that case because the project A
38:18
is linked as overlay, the project A
38:21
is not shown in the project C.
38:24
If you link as attachment, it makes the link model visible
38:28
when its host is link into our third model.
38:32
That will be this image.
38:33
So you model A in Model B as attachment
38:37
and then you link the project B in project C and there
38:40
are all three visible in project C.
38:44
When you link a model in Revit, Revit, in the background
38:48
opens the link model and keep in memory.
38:53
The modeling a project contains, the longer it takes to open.
38:56
So here are sure tip, [INAUDIBLE]
38:58
the link in different worksets.
39:00
So maybe you create a workset, you
39:03
want to keep that and you have your model, architectural model
39:05
and you want to bring the structural model,
39:07
make a workset for the structure,
39:09
make a workset for MEP and place the model from this discipline
39:14
in specific workset.
39:16
And like this, you can decide if when
39:19
you are opening your project do you want to include the links
39:22
or not.
39:24
It's not deleting the link, it's just not
39:26
showing if you do not want to include something
39:30
during the private session, you can get back and include it.
39:34
But it will take less time to open if you do not need it.
39:38
Use workset for Revit links to control also the visibility.
39:42
So you can prepare three reviews, one 3D review
39:46
for each specific worksets.
39:47
And like this you make sure that in each specific review,
39:52
just the specific workset is shown and not the rest.
39:57
And like this, you can control easily
39:59
if each element is associated to the right workset
40:03
because you will see very easily if the elements belonged
40:07
to this especially workset that is shown in the 3D.
40:10
Actually, working with links implies different challenges
40:14
and you should be aware of them.
40:16
And you are working with links, there
40:18
is a limitation of the joining of the element.
40:22
There is a limitation in the interaction between them.
40:25
So you cannot be able to model a door in one model and have
40:31
the work in a different one because it will not cut out
40:34
the opening in the wall.
40:35
If you have two walls in different model,
40:39
they will have no [INAUDIBLE] problem.
40:40
So you have to be aware how did you divide it
40:43
into different Revit models.
40:45
You will get some challenges as well
40:47
when managing the elements names, the numbering,
40:51
the data that identify these elements between the host
40:56
and the link.
40:58
You have to be very careful that you are naming them properly.
41:01
And finally, have to pay special attention
41:04
to manage model standards, the workset, the visibility
41:07
settings, the phases.
41:09
Then once you do a change in one model,
41:12
it should be accordingly changing the different one.
41:17
A link model can be copied any number of times
41:20
that you decide on the host project.
41:22
We will copy link more than on the host
41:25
project for different purposes.
41:27
For example, when we are working and designing
41:30
an housing urban development and we are repeating the same house
41:35
design several times, then we can at the beginning
41:39
of the phase at least just have one house [INAUDIBLE]
41:43
project and copy paste on the host project.
41:46
We are using a [INAUDIBLE] when we
41:49
are working with high-rise towers
41:52
where every specific level are repeated very often.
41:55
So you can just model one level and copy
41:59
paste in the house model.
42:01
But we can do also at the room level.
42:03
So for hospital and hotel is very often where
42:06
rooms are very often repeated, just
42:09
model the room in one Revit project
42:12
and then you copy in the host.
42:14
So when you are copying in a link model
42:16
into your house model, automatically a new name
42:19
is generate.
42:20
You should name it correctly to have a better control of it.
42:24
And you should know as well that you can override in the display
42:27
settings for the whole link like we would have here and do
42:31
manage basically the settings.
42:34
So it will be for the whole Revit wallet
42:37
but also specifically for each of the copies.
42:41
And finally, you should procure to have
42:43
and to use the same faces names in both of the model.
42:47
If you are not using the same phase name in the host
42:51
and in the link, a recommendation
42:53
will be to use face mapping to make sure
42:56
that one phase of the link is of reference
42:60
to the phase of the host.
43:03
So when we are working with links,
43:06
there is something that we can bring into the work flow, that
43:09
is the copy monitor tool.
43:12
So this scheme is showing just a continuation
43:15
of the previous example we saw when
43:17
we were talking about the concept of model Revit file
43:21
and layout Revit file.
43:23
Even if we don't need to separate
43:25
the model and the layout into different file,
43:27
it can be a combination of both, we
43:29
can add a [INAUDIBLE] or a second Revit model
43:34
that we will call level grid Revit.
43:38
We will bring it from the model, but please
43:41
remember it's the positioning and geolocation of the project
43:47
is already currently set up.
43:48
We just save with a new name at this level grid
43:52
and we will link the level grid into the layout into the model
43:57
or in the combination of both.
43:59
We will have the model and the layout in the same Revit file.
44:03
In the level grid, we will create all levels and grid
44:08
and then we will link it on this file.
44:10
And then in the model or layout file,
44:13
we will use the tool of copy monitor
44:17
to coordinate the grids and the level
44:20
from one single source of truth.
44:22
That will be this level grid.
44:24
It will help us to reduce mistake.
44:27
And if there is any change on these level grid file,
44:31
it will be automatically update and notified
44:34
in our model and layout.
44:38
So how does a copy monitor work?
44:40
So in model and layout, we copy monitor all levels and grids
44:45
from the links.
44:45
So you find here in Collaborate tool, in the collaborate menu,
44:50
Copy monitor and then we select the links
44:52
and we start copy monitoring the level from the level
44:57
grid of Revit file to the layout or modify.
45:02
Once we have done this correctly,
45:04
we can share the level grid Revit
45:07
with all the partners and all the stakeholders
45:10
that they are collaborating.
45:11
And like this, we make sure that this model is the only source
45:16
of truth to assure us that we have the correct position
45:20
of the level and of the links.
45:23
If there are any change, we should send everyone
45:27
and give access to these level grid Revit.
45:32
Actually, yes.
45:33
For your information, there are other categories
45:35
that can be also copy monitored as column, wall, floor,
45:39
openings and MEP fixture.
45:42
This image shows how it will work.
45:45
In [INAUDIBLE] you see in the level grid Revit file,
45:50
and here we are in the model, in the Revit model.
45:54
So we see in black, parapet and roof level.
45:59
So once they are copy monitor the levels and the level
46:04
from the level grid is update, so you
46:09
have a new elevation of it, you will get a notification as soon
46:13
as the link is reloaded.
46:17
So you will get a notification and it will say you,
46:19
if you want to accept the difference
46:23
or if you want to move it or you want to postpone,
46:25
you have different solution.
46:28
If there are different levels that have been moved,
46:31
you can select all of them and tell them
46:35
to move to the right position.
46:38
With that said, let's talk now about linking IFC into Revit.
46:42
You can use the information from Industry Foundation Classes
46:46
files in Revit model when you want
46:48
to collaborate with other non-Revit models
46:51
in an open beam workflow.
46:53
To use IFC files in a Revit model,
46:56
you can either open the IFC you are importing into Revit
47:01
or you can link it.
47:02
You open the IFC file in Revit to create
47:05
a new model that use the IFC data as a starting point.
47:09
So if there are later changes on the IFC,
47:12
they will not be reflected on the Revit model,
47:15
is just imported open at once.
47:17
In that case, is usually recommend
47:20
to link the IFC file to an existing Revit model
47:23
to reference the information for additional design work.
47:27
And the model can be update, the IFC can be update
47:31
and then you just need to reload the IFC
47:33
and the change will be shown, the [INAUDIBLE] change
47:36
will be shown from the new IFC in your [INAUDIBLE]..
47:40
Revit support in different IFC format
47:43
based on the International Alliance for Interoperability.
47:47
These are IFC4, IFC2x3, 2x2 and 2x.
47:54
Before opening or linking an IFC file,
47:57
you can specify the template you want to use from another Revit
48:01
file, you can load a single txt file
48:05
that is used to map the IFC classes to the Revit category.
48:10
And you can manually override the Revit categories
48:13
for IFC classes.
48:15
If you have existing design create using AutoCAD,
48:20
you can import this AutoCAD or any other CAD format
48:24
to the [INAUDIBLE] model.
48:26
However, if the DWG or the CAD is update after [INAUDIBLE]
48:31
imported, now Revit will not automatically
48:34
reflect this change.
48:36
Import CAD files or DWGs, they affect negatively
48:41
to the Revit performance.
48:43
You will not be able to find them
48:45
because they can be copying different view,
48:48
they can even be hidden and you will not
48:50
have an easier way to find it.
48:53
If you import the file, you can always explode the DWG
48:58
to the Revit elements but we strongly
49:01
recommend not to explore DWG files in Revit.
49:04
It is possible but this is really not recommended
49:07
because it will really affect the negatively
49:09
to their performance.
49:10
Consider to import them.
49:12
In that case, if you really want to import an empty link,
49:15
consider the import that on an empty Revit model
49:19
and link it into your own model.
49:21
This last [INAUDIBLE] model.
49:24
It makes [INAUDIBLE] model is clean
49:27
and you can easily handle the visibility of the DWG
49:31
by handling the visibility of the link Revit model.
49:35
So in general, to wrap up here, importing DWGs or CAD file
49:41
is not the recommended option.
49:44
If possible, always link the DWGs.
49:48
So if you have existing design created
49:50
using AutoCAD or other CAD product,
49:54
you can link that into our Revit models.
49:58
Linking CAD files is usually the right approach.
50:01
If you link in the DWG or the CAD file,
50:04
they can easily be updated to reflect
50:07
the changes from the CAD file.
50:10
However, keep in mind that in this case,
50:12
you cannot explode the nest in DWG links to Revit elements.
50:17
Why and when should we link that file in the Revit project?
50:22
Use the CAD file as a starting point for your desire.
50:25
It is common that the project team
50:27
receives documentation within DWDs or AutoCAD
50:31
format resulting from a competition or some
50:35
[INAUDIBLE].
50:36
So you can link these documents into your Revit
50:39
as a starting point to create journal.
50:42
You can use also DWGs or CAD format
50:45
to bring the site plan into your Revit project.
50:49
Civil engineers or landscape architect
50:52
often follow what one documentation in different CAD
50:54
format.
50:55
And this is very useful just to link and get it
50:57
in your [INAUDIBLE].
50:59
You can use CAD format to include 2D details in Revit
51:04
instead of doing the detailing in AutoCAD,
51:06
but you can do it in Revit just by bringing
51:09
these DWGs directly.
51:12
In this case, you can also consider to link PDFs.
51:15
Their appearance will be easier to manage if you bring
51:18
in the detail already as a PDF.
51:22
You can place these links from PDF or DWGs
51:25
on views or directly on drafting views.
51:29
In general, it's very useful to collaborate with partner
51:33
not just working without of color on a project like these.
51:37
You can keep working on Revit and collaborate
51:41
with other stakeholders that they are still working on CAD.
51:46
If you want to bring CAD file into private families,
51:50
you have just the option to import them not to link them
51:54
as you have in Revit file.
51:56
So you might want to clean [INAUDIBLE] CAD files in family
51:60
to include 2D information.
52:02
For example, you want to enrich their appearance
52:04
for the day link and the day component families.
52:07
But if possible, it is recommended always
52:09
to create the geometry in Revit not to import the DWGs.
52:12
You can import maybe the DWG, use it
52:15
as a reference to recreate the lines, the symbol lines,
52:19
and then delete it before loading
52:21
the family on the project.
52:23
That would be ideal.
52:25
So when linking DWG file into Revit project,
52:29
consider to create a specific workset if you are
52:33
working on a work-shared model.
52:35
But consider as well to create a Model-in-Place Family
52:39
and select the right category and link the DWG
52:42
inside this Model-in-Place.
52:44
It allows you to cut the geometry of the CAD file,
52:49
always, of course, if it's loading a category family.
52:52
If it's not linked inside the Model-in-Place family,
52:55
then the DWG will not be [INAUDIBLE]..
52:59
It also helps if you want to get the DWG in the Revit schedule
53:05
as a new element.
53:08
As I was saying in the beginning,
53:10
Revit project and DWG can share coordinates.
53:14
So consider to establish a coordinate between DWG
53:17
and Revit files to ensure a correct position.
53:21
Before linking the DWG file into Revit,
53:24
there are some recommended step you should take into account.
53:27
For example, remove any unnecessary data as layer
53:32
that you are not using, that you don't want
53:34
to bring directly in AutoCAD.
53:37
It will impact positively to the performance.
53:41
Keep the CAD drawing in a small area.
53:43
Do not bring and extend CAD if you cannot not need the whole
53:47
extension of it, also affecting to the performance.
53:51
It is recommend to purge and audit the DWG.
53:54
As we say for Revit before, change the proxy graphics
53:59
variable value to one and export proxy object
54:03
to native AutoCAD object.
54:05
Change all the text at font to a present Revit font.
54:11
Arial, for example, would be an example.
54:13
So make sure that the font that they are showing in AutoCAD
54:16
is included in Revit.
54:18
And finally, bind all XRefs if you
54:22
want them to show up in Revit.
54:25
With that said, we are actually at the last section,
54:27
where we will talk about performance best practices.
54:31
Let's talk about that next.
54:33
Updates provide fixes and new feature
54:36
within the same Revit version.
54:39
Revit user working on the same central model
54:42
must collaborate with in the same Revit version.
54:46
It is not possible otherwise.
54:49
But in addition, it is highly recommend to work in the same
54:52
build and hotfix.
54:54
Apparently, it is possible to work on the same central file
54:59
with different build and hotfix, but it
55:02
is a high potential risk you should not
55:05
take to avoid model corruption.
55:08
You can always have a look for new update your AutoDesk
55:11
Desktop app or go through your AutoDesk portal.
55:16
Let's talk about model groups.
55:17
Model groups are an important point
55:19
to pay special attention if we want to keep a high performance
55:23
model.
55:24
In fact, model groups slow file performance
55:27
and increase the file size considerably.
55:29
I understand we often need to work with model groups.
55:33
But they will advise to remove groups
55:36
as soon as they are no longer needed.
55:38
Do not include any Datum Object into a group
55:42
as levels or grids.
55:44
It is highly recommend as well to include elements
55:47
in a group within the same workset.
55:49
Host element and hosting element should
55:53
be always grouped together.
55:55
Remember that the groups should not
55:57
be a replacement of families.
55:59
Anything you can do with a family
56:01
should be done with family and not
56:03
by grouping different element.
56:05
Use groups only if they are at least
56:08
repeated a minimum of instance.
56:10
The news groups is they are just repeated once or twice.
56:15
It's not recommended to nest group within a group.
56:21
Even if you can think that in some situation
56:24
from preliminary design can be a quick solution and helpful,
56:28
it also generates frustration to access
56:30
to the right information.
56:32
And also, when you want to get out of the group,
56:35
again, difficult because you have to close the group,
56:39
close the next group, and so on.
56:41
Finally, do not mirror groups.
56:44
It might work, apparently, in Revit but not in real life.
56:48
So better always to create a right and a left version.
56:52
So for example in equipment usually,
56:54
they do not exist on a mirror version.
56:57
Or if you mirror a door or a group containing a door,
57:01
the swing information of the door will probably be false.
57:07
Let's talk about rooms and space.
57:10
Rooms and space are also affecting
57:12
to the model performance.
57:14
It's convenient only to check the Room Bounding
57:17
option for the link file if it's absolutely necessary.
57:21
If the file is not affected to the new bounding option,
57:25
it should not be selected.
57:27
So Select the link, Edit Type, uncheck the Room Bounding.
57:31
You see here.
57:33
That's by selecting the type and edit it.
57:36
You should unselect the Room Bounding
57:38
if the link is not affecting to the calculation of the room.
57:43
If your model has a warning about overlapping room
57:46
boundaries, this is one of the Warning
57:49
that you should resolve as soon as possible.
57:52
It is affecting the performance of the model,
57:54
but it's also affecting the accuracy of your model.
57:58
So consider to place a room separation
58:00
line on a specific workset for better control.
58:04
You can prepare, as we say before, a 3D view just
58:08
showing this specific workset.
58:10
Unlike this, you can control all the room
58:12
separation line if they are set in the right workset.
58:16
Try to avoid overlapping between room
58:19
or a space separation line between themselves, but as well
58:23
with walls.
58:24
You will get also warning about it
58:26
and is one of the priority one you should take out.
58:31
And finally, Volume Computation should be enabled just
58:35
when really is needed.
58:37
It's taking a lot of resources off the performance.
58:41
And you can see it here, Area and Volume Computation,
58:46
in general, if it's not needed, area, volumes,
58:50
I recommend that you are working only with areas and not
58:55
with volumes.
58:57
Configure project view to optimize Revit performance.
59:01
The setup of the view will also affect the performance
59:04
of your Revit model.
59:05
Specify a simple drafting view as a starting view
59:09
for your Revit project.
59:11
It will help you to improve the performance
59:13
when opening the project.
59:14
Revit will take less resources to open a simple view
59:19
than to recreate a 3D complex geometry that maybe you don't
59:23
need to access at that point.
59:25
You can also use section boxes to limit the visible geometry
59:29
in 3D views.
59:31
So Revit does not need to calculate the whole geometry
59:33
of your project if you are only working on a specific area.
59:37
Avoid to use the common permanently hiding
59:42
elements in view.
59:43
Turn off the categories that you don't need on the visibility
59:48
graphic or in the view templates and assign the right level
59:52
of detail to this view.
59:55
It will take less resources to calculate
59:58
the geometry and the view itself.
60:01
When working with many views that you are not using,
60:05
it's recommended that you close open views.
60:08
It will take less resources than having all views open
60:12
at the same time.
60:13
We often create work in progress view no longer needed.
60:18
It's convenient to minimize the number of them in your project.
60:21
So regularly, try to delete unused views.
60:25
When you use the Paste Aligned tool to views
60:27
that they are closed, the target views
60:30
will open and close automatically.
60:33
You can improve the performance of this common Paste Aligned
60:37
by opening first all the targeted views
60:40
before the operation of Pasting Aligned.
60:44
Minimize the view depth when it's possible in elevation,
60:49
in plans, or section views.
60:51
Revit will take less resource to recreate the geometry
60:54
since there is less quantity of object to calculate
60:58
in the background.
60:59
Even if they are hidden, this element by another element,
61:02
it takes less resources.
61:05
So for the same purpose, you can also
61:07
consider back clipping views to reduce the quantity of geometry
61:11
maintained on these view.
61:14
Thank you for joining.
61:16
I hope you find this session informative,
61:19
and you could take out some insight for your next project.
61:23
If you need any help from AutoDesk,
61:26
do not hesitate to contact your customer success
61:28
manager or your designated super specialist or in any case,
61:33
your AutoDesk partner.
61:36
They would be happy to help.
61:39
Thanks again for joining.
61:40
And thanks for watching.

[MUSIC PLAYING]
00:08
Hello, everyone, and welcome to this presentation
00:11
about setting up Revit for AEC project.
00:14
Thank you for joining.
00:16
My name is Daniel.
00:17
I'm working as a designated support specialist in Autodesk
00:21
and I'll be presenting today.
00:23
By the end of today's session, you'll
00:25
learn about what you need to do before starting
00:29
the project in Revit.
00:31
We will talk about coordinate system,
00:34
we will see what take into account in the model strategy,
00:39
how to know the best of the model maintenance,
00:43
how to work with different links in Revit.
00:47
And we will need some good practice about performance.
00:52
Before starting, I want to share the safe harbor statement.
00:56
Essentially, it says the product and service and features are
01:01
subject to change and purchasing decisions should not be made
01:04
based on this presentation.
01:06
And let's move to the first section,
01:08
what these recommend doing before to start the project.
01:12
In general, companies working with Revit
01:14
invest time and effort in developing templates
01:18
according to their own standards because they
01:21
know the template help to maintain
01:23
quality and consistency across everyone within a field.
01:28
They also save users a lot of time
01:31
by setting up the necessary standards in advance
01:35
so people don't have to start everything from scratch.
01:39
This is especially important for some discipline,
01:43
the structural design and they MEP discipline
01:46
because they have to accomplish in general very
01:49
complex calculation.
01:50
And there are very specific settings
01:52
that they are only specific to this discipline.
01:56
I'm thinking, for example, about reinforcement parameter,
02:00
this is only important for structural engineers
02:03
in general.
02:04
MEP or architects don't need to have
02:07
all these setting correctly set up in the template.
02:11
Is the same with other setting for MEP
02:14
or structural engineers.
02:16
So where can you find the various project templates
02:20
in Revit?
02:21
When Revit is installed, default Revit templates
02:26
generate Autodesk has been saved in the following path.
02:31
So you have in C, program data, then from the Autodesk, Revit
02:36
and the version of Revit and then templates.
02:40
Please note that the file extension for Revit templates
02:43
is not rvt coming from the right [INAUDIBLE],,
02:46
but this rte from Revit template.
02:49
There is a different one for Revit
02:50
families and Revit family templates.
02:54
As we said before, you can create new project templates
02:57
and save them in the same location or a different one.
03:01
In Revit, through file, option and file location,
03:05
you can specify the default location of the one Revit
03:09
will show up when creating a new project.
03:12
To facilitate the selection of the template,
03:14
when do you want to create a new project?
03:16
If you do not see in there the specific template
03:20
you want to bring it to your new project,
03:24
then you can always browse for it.
03:26
So you see it here.
03:30
By Browse, you can select the template
03:32
that it's maybe [INAUDIBLE] and all that.
03:35
Finally, all these setting definition path
03:38
and other variables can be managed through a simple txt
03:41
file.
03:42
It's the Revit.ini file.
03:44
As I say, it's a simple txt file and very
03:48
useful to distribute across the whole organization
03:51
and make sure that all user get the right path to the company
03:55
templates and to other variables that you want to standardize
03:60
What could be included in project templates?
04:03
Anything included in project template
04:05
is subject to customization.
04:08
We can even divide in 3D groups or you can include it
04:12
in project templates.
04:13
We are grouping by visibility, content and setting.
04:17
In this slide and the following one,
04:19
you see a list of the main topics included in each group.
04:24
In relation with visibility, you can include viewport types,
04:29
you can bring views, already defined views, schedules,
04:33
sheets and legends.
04:35
You can include view types, you can prepare the browser
04:40
organanization as you desire.
04:43
You can include filter.
04:44
And what is very important, you can put view templates or color
04:49
schemes.
04:49
We will talk about view templates.
04:52
About content, you can include the naming standard
04:56
you are used to work in the company,
04:60
you can bring annotation family, title blocks,
05:04
any kind of family outlook, loadable
05:05
and system family can be already included in the templates.
05:09
All type of parameter, project parameters, shared parameter
05:13
and global parameter can be included as well.
05:16
And you can prepare some placeholder links
05:18
that you will lead that change by the right model.
05:23
Related to Settings, we can include many points.
05:27
Here, a list of the main ones.
05:30
So we can bring material libraries, object style.
05:34
We can define the settings to export the DWG.
05:39
We can have the line of style, and you see here
05:43
in the screenshot.
05:44
Line wave, line pattern, we also include it,
05:48
hatch pattern as well, MEP setting
05:51
and the structural settings, revisions,
05:54
the units of the project.
05:57
You can predefine worksets and phases.
06:02
There are other templates very important to take into account
06:05
to assure a standardization and maintain
06:07
the quality and consistency of your project.
06:09
These are the view templates we talk about before.
06:12
All these are view template.
06:14
So a view template is a collection of view properties.
06:18
As the scale, the detail level, some visibility
06:21
settings and so on.
06:24
View templates are used to a standardized project views.
06:28
You can in View Templates, you can create templates
06:31
from Current View, then you can apply the template
06:35
to the current view or to a different one.
06:38
And you can manage the view templates
06:41
and change the visibility settings.
06:44
View template as best practice, prepare them
06:48
before starting a project.
06:50
Even if you will define and [INAUDIBLE] step by
06:53
step building the project life.
06:56
Many of them view templates have been improved
06:60
during the project life of our Revit project,
07:03
therefore we decide to recover them from different projects
07:06
to the current one.
07:08
There is a very useful tool allowing you to transfer them
07:11
between two Revit client or between a family and a project.
07:16
It is called the transfer project standard tool.
07:20
Actually, there are multiple combinations
07:21
you can transfer projects standard between doing
07:24
Revit project, Revit template or Revit families.
07:28
Any combination that you want between all these type.
07:31
So let's see how to transfer project standard.
07:34
To transfer projects standard, first of all,
07:36
we need to open in the same Revit session
07:39
both of the files.
07:41
In the target file, you have to be active in the target file
07:45
and then go to Manage tab, Settings panel and Transfer
07:48
Project Standards.
07:51
Select the source project for Copy from in case
07:54
that you have different files open there.
07:58
And then to select the desired project standard
08:01
that you want to bring, there are different categories
08:04
that you can select.
08:06
We will see in the next slide, which one and you will bring
08:09
into your current project or the families
08:12
that they are included in this category.
08:15
If there are duplicate types, a duplicate type dialogue
08:19
will be displayed.
08:20
You will have the possibility to select the option
08:23
to override the family that you have in your current project
08:27
to bring only the one that they are new
08:30
or to cancel the whole operation.
08:33
So what can we include when transferring project standards.
08:37
There is a long list of categories
08:39
we can recover from one project to another.
08:42
As you can see in this slide that actually is not
08:44
showing all of them but you can get
08:47
an overview of the different topic you can include.
08:50
In the right, you can see a screenshot
08:51
of the different categories that you can get
08:54
and you can select all of them, you
08:56
can just select the one that you decide to transfer
08:59
from one project to another.
09:02
When transferring project standards,
09:04
there are a few good practice to take into account.
09:08
In the out of the box solution, there
09:10
are some limitations to transfer a specific family or type.
09:14
It is just not possible to select which type
09:16
or which family from specific categories
09:19
you want to transfer.
09:20
It is only possible to select the whole category.
09:23
If the idea is to get back in your project specific families,
09:26
you always have the possibility to copy paste
09:30
or to save in your window folder and log it again
09:34
in your project.
09:35
Keep in mind that you can also use Dynamo to load
09:38
multiple families at once.
09:40
It can be very useful to automate the process
09:43
at the beginning of the project or when
09:46
changing to a new phase.
09:48
It is convenient to transfer system families that
09:51
rely in other system families at once
09:54
because you will make sure that their relationship is correctly
09:58
maintained.
09:59
We can repeat the same tip for view template and filter.
10:03
They should be transferred together not
10:04
to lose the relationship of the filter that are included
10:08
in each specific view template.
10:10
Be careful, if the target project contains already viewed
10:14
templates and filter with the same name, in that case,
10:18
you might want to rename or delete them before.
10:22
There are some items in Revit not subject to be transferred
10:26
between projects.
10:27
These are elevation or section types and the visibility
10:30
setting for Revit links.
10:33
As you might be aware, it is not possible to store system family
10:36
out of the Revit project.
10:39
System family rely are safe within the session of the Revit
10:43
project.
10:44
It is a good practice then to save
10:46
system family as wall, floor, ceilings, stairs, pipes
10:50
or ducts, et cetera of the system family
10:53
within a Revit project.
10:54
And every time you need them, get the family type
10:58
back from this project by copy pasting it.
11:01
Consider to have then in that case
11:04
a specific project for each specific category.
11:07
For example or by discipline you can
11:10
get one project for architectural system
11:14
family, one project for MEP system family
11:17
or you can do it by categories.
11:20
So let's surely talk about the coordinate system.
11:23
Actually, coordinate system represent
11:26
by themself a big topic.
11:27
A whole presentation would be needed to address and explain
11:31
it properly.
11:32
However, I want to include in this presentation
11:35
a short statement on this because it's really
11:38
important that when sending out your project,
11:41
you position correctly your project.
11:44
In where you have the possibility
11:45
to specify the geographic location using
11:48
the address or the near city or the latitude and longitude.
11:53
This is very helpful for solar studies weather analyse,
11:57
et cetera.
11:59
But please, know this is not georeferencing your model.
12:03
Usually, we need to do georeference our new model
12:06
and therefore we need to define the survey
12:08
point to match with a known point in the world.
12:11
We can use survey coordinates from the civil engineer
12:14
for example or we can determine the coordinates of a known
12:17
location, such as the intersection of the property
12:21
line or a geodetic survey marker.
12:24
Very probably, it will be needed to protect the project North,
12:29
to define it correctly that epsilon axis of the survey
12:33
point.
12:33
Or maybe is the countrary and you
12:36
can rotate the project North before starting
12:38
to model anything.
12:40
The project based point will be automatically updated
12:43
with the right coordinate as soon as you have correctly
12:46
defined the survey point.
12:47
However, it will be convenient that you define properly
12:52
the project based point in a specific location
12:54
in your project, maybe the corner of the project
12:57
to establish a reference for the [INAUDIBLE]..
13:01
Once we have accomplished that, we
13:03
can start importing or linking other models or other CAD files
13:08
And we can use the appropriate positioning option.
13:11
So maybe you want to link auto by share coordinates, Auto
13:17
origin to origin or automatically
13:20
project based point to project based point.
13:22
If we need to coordinate the location of multiple building
13:26
or different parts of the same building.
13:28
It is very common to use them, the shared coordinates.
13:31
All the shared coordinates, why we will use?
13:34
Shared coordinate are used for remembering
13:36
the multiple position of different interlinked files.
13:40
Those interlinked files can be ultra [INAUDIBLE] file
13:43
or it can be a combination from Revit DWGs or the [INAUDIBLE]
13:47
files.
13:48
As I say, and that is a very short overview
13:51
of the possibility to position and to your reference
13:54
[INAUDIBLE] models.
13:56
Let's move then now to the next section about model strategy.
14:00
What is LOD?
14:02
LOD stands for Level Of Development.
14:05
Data specification combines how an element geometry is defined.
14:10
They associate information attached
14:12
to it and the evolution through the different phases
14:16
of the project.
14:17
So actually, three topics.
14:19
Remember, geometry, information, associate
14:23
to the element and the evelotion through the phase,
14:26
different phases.
14:27
LOD start at level 100, at the very beginning of the project
14:32
doing the conceptual design phase
14:34
and reaches 500 when it's in operational phase.
14:40
During different LOD steps, the geometry representation
14:44
of the element is getting more and more accurate
14:48
but at the same time we are adding
14:49
more and more information to that specific element.
14:53
On the table on the right, you can
14:55
see an example of the proposed geometry
14:59
level that is associate to each specific level of development.
15:03
And you can see also different information
15:06
that is recommended to have on each specific LOD.
15:11
In reality there is not a clear maximum size of the model.
15:14
Actually, performance is not only dependent on the size
15:20
but is really dependent on the complexity of the model, which
15:24
is much more difficult to identify that the size
15:26
of [INAUDIBLE].
15:27
The experience will let you know and to understand
15:29
ideal the size of the project depending on the use case
15:34
you are handling.
15:35
Sometimes we hear 400 megawatt is something ideal maximum
15:39
size, but again it does not apply to every model.
15:44
Very often, we will need to break up
15:47
then the project in different model
15:49
to avoid working with a very heavy file.
15:53
For example, in architecture and that's
15:55
the screenshot that you can see there,
15:57
a good practice is to break up the model in different part
16:03
like this one.
16:05
In the bottom we have the basement
16:07
then we have the commercial part, the office level
16:13
and the residential level.
16:15
That will be a good practice to divide architectural model
16:19
for example.
16:20
Actually, we can also have the facade in a different model
16:24
and multiple combination.
16:26
Another good practice when a splitting model
16:29
will be to split it by different disciplines model.
16:32
You will have one model for architecture,
16:34
one model for MEP, one model for a structure and so on.
16:38
Another solution is to prepare and define
16:40
many modeling zones defined by your scope box for example
16:44
and then start splitting from there.
16:46
So typically, in architecture, we are split by external shell,
16:52
vertical communication stair, an elevation shaft interior spaces
16:58
for example or zone in as we saw before for residential,
17:02
commercial, and office.
17:06
In a structural design is not the same,
17:09
we often split by dilatation or construction joints.
17:12
In MEP is, again, different and we are split by system
17:17
independently if the system is 30 meters high.
17:21
It is important, of course, in MEP
17:23
to have closed system in the same model.
17:26
As you can imagine, the process is not
17:29
easy to achieve but you will find
17:32
that this a big improvement in the performance
17:36
once you do the correct split of the model.
17:40
We've just seen how to split models.
17:42
Views, sheets, and schedules are also
17:46
impacting the performance of the Revit file.
17:49
You can think as well to minimize splitting the model
17:52
and creating a container file to link your model
17:56
and create there all the views, sheets, and schedule.
18:01
This is particularly useful for architects
18:04
that very often need to deliver many, many views
18:07
from the same floorplan.
18:08
So let's have a look to this diagram.
18:11
At the top, we start our project by choosing the correct project
18:15
template as we were saying at the beginning
18:17
of the presentation.
18:18
Then once we have our project open and safe,
18:22
let's call project model, we define on this file
18:27
just the coordinate system properly.
18:30
So we define the survey point and we
18:33
positioned the project base point where we really need it.
18:38
But we do not model anything complete one.
18:40
We will keep this file, let's call, I clean
18:45
file that we can use as many times as we want.
18:48
So we will save this file one as model file.
18:53
So the model project file is this one
18:56
and we will save again this one as a layout.
19:02
We link the model into the layout.
19:05
So we will use the model 90% of our time to model everything
19:12
from a project and the layout to create views, to create sheet,
19:18
and to create a schedule if needed.
19:21
Let's see a bit more in detail.
19:22
What should these model file contain?
19:26
It contains all valid model elements.
19:30
We should create some views as working in progress views
19:33
but we should minimize the number of views, sheets,
19:36
and schedules.
19:37
We minimize as well the number of annotation.
19:40
I suggest we prepare one view by level, one section, and one
19:45
elevation that usually we need it also lay layout.
19:49
And we prepare one for each specific ready to be printed.
19:54
They can be shown in the layout later on us by DMV
19:58
we will see later on how we link it there in that the case.
20:02
So actually because you are working in the model,
20:07
then most of your time it's good to have
20:09
from each specific level, elevation and section
20:13
you are usually printing one Revit view but not
20:19
What should be then included in the layout?
20:21
We have linking the model Revit file into the layout.
20:25
You can also consider having one layout for the normal plans
20:30
and one for details.
20:31
We can call it layout plans and lay out details.
20:34
But in general, I would say minimize
20:36
the number of layout file because it
20:38
helps you to avoid numbering issues having
20:42
a better control of the naming and numbering of the sheets.
20:46
Create all views that you needed to be
20:49
printed on these layout file.
20:52
If needed, you can duplicate views
20:54
and duplicate that's dependent and crop to fit in the sheet.
20:59
For other needs, consider to create
21:01
views for different concept as for material, ceiling
21:06
plans, concept of door and so on, all these does not need
21:11
to be created in the model.
21:13
So we needed in layout file assign view template
21:17
to control the visibility.
21:19
You can override in visibility graphic by host view,
21:24
by linked view and by custom.
21:26
So it means by default when you are
21:29
linking the model in the layout, views
21:32
will appear s host to you.
21:35
It means that the view template is
21:38
controlled by the layout file.
21:41
If you want for a specific view to be control
21:45
the visibility setting from the model file,
21:49
then you have to specify by link view
21:52
and you just select the view from the model file
21:56
that you want to represent in the layout file.
21:59
Custom will be a mix solution where
22:01
you will choose the view from the model file
22:04
that you want to bring in the layout.
22:07
But still, you can customize and do some changes in the layout.
22:12
If you are creating a schedules or quantities take off
22:16
in the layout, remember that you should include links.
22:20
If not, it will be empty of course.
22:22
Annotation is recommended to do it in the layout
22:25
because then the model file will be more performant
22:29
and maybe you can consider to use a scope
22:32
box to control the crop region of multiple views.
22:36
And like this one, you are placing different floor plans
22:40
in the layout in the sheet.
22:41
They are all sitting in the same place
22:43
and they are not jumping out.
22:47
So here we find a very schematic overview of both Revit file.
22:53
On the left, you can see what we call before the model Revit
22:58
and on the right, the layout.
22:60
As you can see on the Revit, there
23:02
is one floor plan by level.
23:04
Actually, we create one floor plan by level
23:07
and there are no sheets.
23:09
In sheets, it's empty.
23:12
But in the layout Revit file, we have duplicate [INAUDIBLE]
23:18
each specific level because they are not fitting in the sheet.
23:23
So actually we have four different views
23:27
for each specific level.
23:29
And moreover, we are having some views
23:32
that they are showing the concept, as we say,
23:36
circulation concept, door concept, floor finish
23:39
concept and so on.
23:41
So we are creating use floor plans
23:45
that they are not existing in the model.
23:48
We will create the schedules and quantity as well
23:51
and we will do all the sheet, we will create it here
23:55
in the layout.
23:57
[INAUDIBLE] existing here.
23:58
As you can imagine, all these is increasing.
24:01
If we will combine both of model and view sheets
24:06
and quantity in the same file, the size
24:09
will be sometimes not easy to handle.
24:13
So therefore, it will be a solution to a split it
24:16
in model and layout file.
24:19
So now, let's move to a different topic, worksharing.
24:22
What is worksharing?
24:24
Work sharing is a design method that
24:26
allows multiple team members to work on the same project
24:30
model at the same time.
24:32
On work sharing project, team member
24:34
are assigned to a specific functional area to work
24:37
and that is managed by the worksets.
24:40
Non-worksharing private project [INAUDIBLE] or city neighbor,
24:44
you start using worksharing in the project
24:48
as soon as you create the first worksets.
24:52
A workset is a collection of elements in a project.
24:56
They only exist in workshared projects as we said before.
24:60
Revit use the technology of workset
25:03
as a mechanism to enable multiple user to collaborate
25:07
on one central model.
25:09
And they are taking the ownership of the element
25:12
when they are attached to one of these worksets.
25:16
So now that we define what is a workset,
25:19
you can create workset based on different functional areas
25:22
such as the following, so for example
25:24
for architectural and structural engineers,
25:26
often, we create workset for interior
25:29
or exterior for the site or the facade, our furniture
25:34
and so on or in MEP, we often create a workset for HVAC,
25:41
workset for electric car, workset for plumbing.
25:44
And if the project is very big and complex,
25:47
you can subdivide as many walls of that you want.
25:51
Maybe you want to create plumbing
25:53
for a specific system as cold water in one water,
26:00
hot water in another, and so on.
26:03
That is an important distinction between working
26:06
with ownership of a workset and borrowing from a workset.
26:10
In fact, when you make a workset editable in Revit,
26:14
you are taking exclusive ownership of all the objects
26:19
that they belong to these specific workset.
26:22
Only one user can at one point be the owner of one workset.
26:27
Two people cannot be owner of the same workset.
26:30
But however, all team member, even if somebody
26:33
is the owner of the specific workset,
26:35
all team member are able to see in the project all the workset
26:40
even if they are not owned by a different team member.
26:43
But there is also the possibility
26:45
that you are not taking ownership of a specific workset
26:48
but you are borrowing a specific workset.
26:53
First option is in general a more stricter and less risky
26:59
but the second one gives you more flexibility.
27:02
Of course you can use a combination of them
27:05
and take the ownership for a specific workset
27:07
and let the others to use their borrowing option.
27:11
So with that said, let's move to a different topic
27:14
about model maintenance.
27:16
There are a few regular work to do to keep a healthy
27:20
and perform a model.
27:22
So if you are familiar with AutoCAD, the audit command,
27:25
you can understand how audit can help you to keep up performing
27:29
model in Revit as well.
27:31
The audit function scans, detect and if it's possible,
27:37
it will fix corrupt element in the model.
27:40
But keep in mind that it does not
27:42
provide you a feedback of which element has been fixed.
27:46
You have the opportunity to audit model
27:49
when opening a Revit project.
27:51
If you want to audit, you have to close it and open it again.
27:54
For workshare model, make sure that all user close their work
27:59
and they do not open again.
28:01
They'll all save local file.
28:04
If I create new one from central, if they do not do so,
28:08
you'll get back the fix error in your central file.
28:12
Auditing a model can be time consuming.
28:14
If the model is healthy it should not be very significant,
28:18
but still it can be time consuming.
28:21
So therefore we recommend to do it weekly or even daily
28:25
because you make sure that it will not
28:27
take too much time the next time that you will audit it.
28:33
And be aware that you can audit Revit project files
28:36
but you can also audit Revit families
28:39
and audit Revit templates.
28:42
Purge is also a known command in AutoCAD.
28:45
You have it as well in Revit.
28:47
It remove unused element as views, families, groups, et
28:52
cetera from the project to improve the performance
28:55
and reduce the file size.
28:57
But before purging, it is recommended
28:60
that you create a backup project file in case you
29:02
want to get back some elements that were included in the model
29:07
library but they were not in use.
29:09
In general, it's recommend not to purge all
29:12
that you find in your project but to Check None at first
29:16
and select exactly what you decide to purge.
29:19
These actually should be done by somebody
29:23
with some responsibility in the project.
29:26
Keep in mind then that when you're
29:28
working with workshared project, all workshared should
29:32
be open to use these tools.
29:34
And models that contain elements load
29:38
for a future phase in the project
29:40
as it can be that you have views,
29:42
some families, materials, any content that you want
29:46
to use in a future has been load previously,
29:49
will be also purged if you do not control it.
29:52
So be careful to purge something you need later.
29:55
Therefore, it's recommended that is done by the BIM
29:59
manager or the BIM coordinator.
30:01
You can also compact central models when synchronizing.
30:05
What is compacting central models achieving?
30:09
This helps reduce file size when saving workshare project.
30:13
So it's just value for workshared project.
30:15
The process of compacting rewrite the entire file,
30:20
it remove part that they are no longer needed
30:24
and therefore it will save some space.
30:26
Actually what this is doing is it's readjusting the database
30:30
and readjusting how the information is
30:35
stored in a more efficient way.
30:38
It is recommended to periodically select
30:41
the option of compact central model
30:44
when synchronizing to central.
30:46
In general, it's not significant time consuming
30:49
but the process can sometimes take longer
30:53
than normal synchronize takes.
30:56
So it's recommended to do if you can interrupt
31:00
your workflow for a bit longer.
31:04
The benefit of a compacting central model
31:08
is just as we say, for version model,
31:12
is not affecting the local file from the central model,
31:18
that you extract from the central model.
31:20
And this is not possible to do it for normal none
31:24
workshare Revit project.
31:27
So therefore because it's not extended to local files,
31:31
it is recommend that you are creating new local file
31:35
at the beginning of your work day
31:36
and not to open your old local file
31:40
because you will lose the power of compacting a central model.
31:46
It is very usual for Revit model get very different warning
31:50
types.
31:51
So when working on a Revit project,
31:53
you can review a list of warning methods
31:56
to use and to find issues that might
31:59
require review and resolution.
32:02
Unlike error methods, warning methods
32:05
do not prohibit the current action.
32:09
You do not realize when a warning occurred.
32:12
You are modeling and modeling and suddenly you
32:14
realize that you have a couple of hundreds warning,
32:18
but the warning they just informed you
32:20
that a situation might not be your intention
32:24
and you can then decide if you want
32:26
to correct or to ignore it.
32:29
So it's recommend that you review
32:31
and you correct the warnings regularly not
32:35
to come at the end of your project
32:36
without enough warnings.
32:38
And you should know that you should prioritize the warning
32:41
that they are involved in geometry and calculation,
32:44
how they can affect your performance of your model
32:48
or the quality of the model.
32:50
So in general, there are warning that they do not
32:53
affect performance and there are warning they do affect.
32:57
But you should concentrate resolving the one
33:00
that they are giving some inaccuracies in the drawings
33:04
or the one that they are about duplicate element or clash
33:08
detection elements because all these error or warnings
33:12
actually have an effect of the cost estimation of the quantity
33:18
estimation, the quantity they got,
33:20
and the clash detection of your project.
33:23
So warnings can be exported in a HTML file.
33:29
This file will include the error message
33:32
and the ID of the element that they are impacting.
33:36
So we recommend that you use these ID
33:38
that you find on the HTML to find the element in Revit
33:43
and then check if you should repair or not
33:45
and understand where the problem is happening.
33:49
And finally for this section, is also
33:51
recommend to manually review your model.
33:54
There is a way to have automate the process.
33:57
You can use working in process schedules in Revit
34:00
to review the data and check if the parameter are populated
34:05
correctly.
34:06
So for example, you can use the grouping
34:09
and the conditional formatting in schedule
34:12
to identify elements with parameters
34:14
that are usually out of range.
34:17
It is a good practice to prepare some work in progress schedule
34:21
to continue monitoring the quality of the model.
34:24
So for example, you see here on this image,
34:27
there is a scheduled for walls that we are controlling
34:32
the height of the wall.
34:34
So we know that this specific family type of wall,
34:38
there is [INAUDIBLE] basic wall interior
34:41
is usually room height.
34:43
So if suddenly it's not going to the--
34:47
it's just 1 meter or 1 meter
34:53
actually it's jump out in a different line
34:57
and you identify that.
34:58
It might be an currency.
35:00
So that's a way to check if the model is correct or not.
35:05
You can do it also to see the high position of the door
35:08
or of the window.
35:10
So if this specific family window are not
35:15
sitting 80 centimeter from the floor,
35:17
then it jumps out of the list and you can easily look for it.
35:23
So let's jump now to the next section
35:25
about how the work with links.
35:28
In Revit, we can link and we can as well
35:32
import different file format.
35:34
So we can link Revit models, we can link or open IFCs,
35:40
we can link or import CAD format as dwg, dxf, dgn, sat, SketchUp
35:49
or 3dn.
35:50
But actually, there are other type format
35:53
that we can bring as topographies from dwg
35:57
as well or from pixable, we can link
36:00
point cloud, coordination model from Naviswork, Nvidia NVS, VC.
36:06
We can link or import PDF and images.
36:10
Let's talk about Revit models link in driving model.
36:14
We are linking driving model into Revit model
36:17
for different purposes.
36:18
So usually we are going for putting together
36:22
different buildings such as a campus, where
36:25
we link different building into one file collecting
36:29
all the different building together.
36:31
We are doing as well to put together a different part
36:34
of a same large building.
36:36
So it can be that the facade is one Revit model,
36:42
the interior is a different one.
36:44
Maybe the side is another model and so on.
36:48
We are doing also to coordinate disciplines are
36:51
as the one we see in the image.
36:52
So on the top right, we have the architectural model
36:57
and on the bottom right, we have the structural model.
37:00
And finally, we can do it as well
37:03
from the workflow we saw before to bring the model
37:07
into our layout model.
37:08
So we do all the modeling in the model
37:13
and we define and we link this one in the layout
37:17
that we define.
37:19
Links model are listed in the Revit links
37:23
branch of the project browser.
37:25
So here, Revit automatically update the link
37:29
when you open the project.
37:31
That's why you can always have these links
37:34
if you go to Manage, Manage Links
37:36
and then just reload them [INAUDIBLE],,
37:39
if you want to reload the link model
37:41
during your private session.
37:43
Be aware that you should set up correctly the link reference
37:47
type.
37:48
You have the possibility to choose
37:50
between overlay and attachment.
37:52
Overlay does not load the link model
37:56
when its host is link into another model.
37:59
And by default, this is the setting
38:01
you get when you link the model.
38:03
So that would be the schema represented in this game.
38:08
So you will link the project A in the project B as overlap
38:12
and then you link the project B in project C.
38:15
In that case because the project A
38:18
is linked as overlay, the project A
38:21
is not shown in the project C.
38:24
If you link as attachment, it makes the link model visible
38:28
when its host is link into our third model.
38:32
That will be this image.
38:33
So you model A in Model B as attachment
38:37
and then you link the project B in project C and there
38:40
are all three visible in project C.
38:44
When you link a model in Revit, Revit, in the background
38:48
opens the link model and keep in memory.
38:53
The modeling a project contains, the longer it takes to open.
38:56
So here are sure tip, [INAUDIBLE]
38:58
the link in different worksets.
39:00
So maybe you create a workset, you
39:03
want to keep that and you have your model, architectural model
39:05
and you want to bring the structural model,
39:07
make a workset for the structure,
39:09
make a workset for MEP and place the model from this discipline
39:14
in specific workset.
39:16
And like this, you can decide if when
39:19
you are opening your project do you want to include the links
39:22
or not.
39:24
It's not deleting the link, it's just not
39:26
showing if you do not want to include something
39:30
during the private session, you can get back and include it.
39:34
But it will take less time to open if you do not need it.
39:38
Use workset for Revit links to control also the visibility.
39:42
So you can prepare three reviews, one 3D review
39:46
for each specific worksets.
39:47
And like this you make sure that in each specific review,
39:52
just the specific workset is shown and not the rest.
39:57
And like this, you can control easily
39:59
if each element is associated to the right workset
40:03
because you will see very easily if the elements belonged
40:07
to this especially workset that is shown in the 3D.
40:10
Actually, working with links implies different challenges
40:14
and you should be aware of them.
40:16
And you are working with links, there
40:18
is a limitation of the joining of the element.
40:22
There is a limitation in the interaction between them.
40:25
So you cannot be able to model a door in one model and have
40:31
the work in a different one because it will not cut out
40:34
the opening in the wall.
40:35
If you have two walls in different model,
40:39
they will have no [INAUDIBLE] problem.
40:40
So you have to be aware how did you divide it
40:43
into different Revit models.
40:45
You will get some challenges as well
40:47
when managing the elements names, the numbering,
40:51
the data that identify these elements between the host
40:56
and the link.
40:58
You have to be very careful that you are naming them properly.
41:01
And finally, have to pay special attention
41:04
to manage model standards, the workset, the visibility
41:07
settings, the phases.
41:09
Then once you do a change in one model,
41:12
it should be accordingly changing the different one.
41:17
A link model can be copied any number of times
41:20
that you decide on the host project.
41:22
We will copy link more than on the host
41:25
project for different purposes.
41:27
For example, when we are working and designing
41:30
an housing urban development and we are repeating the same house
41:35
design several times, then we can at the beginning
41:39
of the phase at least just have one house [INAUDIBLE]
41:43
project and copy paste on the host project.
41:46
We are using a [INAUDIBLE] when we
41:49
are working with high-rise towers
41:52
where every specific level are repeated very often.
41:55
So you can just model one level and copy
41:59
paste in the house model.
42:01
But we can do also at the room level.
42:03
So for hospital and hotel is very often where
42:06
rooms are very often repeated, just
42:09
model the room in one Revit project
42:12
and then you copy in the host.
42:14
So when you are copying in a link model
42:16
into your house model, automatically a new name
42:19
is generate.
42:20
You should name it correctly to have a better control of it.
42:24
And you should know as well that you can override in the display
42:27
settings for the whole link like we would have here and do
42:31
manage basically the settings.
42:34
So it will be for the whole Revit wallet
42:37
but also specifically for each of the copies.
42:41
And finally, you should procure to have
42:43
and to use the same faces names in both of the model.
42:47
If you are not using the same phase name in the host
42:51
and in the link, a recommendation
42:53
will be to use face mapping to make sure
42:56
that one phase of the link is of reference
42:60
to the phase of the host.
43:03
So when we are working with links,
43:06
there is something that we can bring into the work flow, that
43:09
is the copy monitor tool.
43:12
So this scheme is showing just a continuation
43:15
of the previous example we saw when
43:17
we were talking about the concept of model Revit file
43:21
and layout Revit file.
43:23
Even if we don't need to separate
43:25
the model and the layout into different file,
43:27
it can be a combination of both, we
43:29
can add a [INAUDIBLE] or a second Revit model
43:34
that we will call level grid Revit.
43:38
We will bring it from the model, but please
43:41
remember it's the positioning and geolocation of the project
43:47
is already currently set up.
43:48
We just save with a new name at this level grid
43:52
and we will link the level grid into the layout into the model
43:57
or in the combination of both.
43:59
We will have the model and the layout in the same Revit file.
44:03
In the level grid, we will create all levels and grid
44:08
and then we will link it on this file.
44:10
And then in the model or layout file,
44:13
we will use the tool of copy monitor
44:17
to coordinate the grids and the level
44:20
from one single source of truth.
44:22
That will be this level grid.
44:24
It will help us to reduce mistake.
44:27
And if there is any change on these level grid file,
44:31
it will be automatically update and notified
44:34
in our model and layout.
44:38
So how does a copy monitor work?
44:40
So in model and layout, we copy monitor all levels and grids
44:45
from the links.
44:45
So you find here in Collaborate tool, in the collaborate menu,
44:50
Copy monitor and then we select the links
44:52
and we start copy monitoring the level from the level
44:57
grid of Revit file to the layout or modify.
45:02
Once we have done this correctly,
45:04
we can share the level grid Revit
45:07
with all the partners and all the stakeholders
45:10
that they are collaborating.
45:11
And like this, we make sure that this model is the only source
45:16
of truth to assure us that we have the correct position
45:20
of the level and of the links.
45:23
If there are any change, we should send everyone
45:27
and give access to these level grid Revit.
45:32
Actually, yes.
45:33
For your information, there are other categories
45:35
that can be also copy monitored as column, wall, floor,
45:39
openings and MEP fixture.
45:42
This image shows how it will work.
45:45
In [INAUDIBLE] you see in the level grid Revit file,
45:50
and here we are in the model, in the Revit model.
45:54
So we see in black, parapet and roof level.
45:59
So once they are copy monitor the levels and the level
46:04
from the level grid is update, so you
46:09
have a new elevation of it, you will get a notification as soon
46:13
as the link is reloaded.
46:17
So you will get a notification and it will say you,
46:19
if you want to accept the difference
46:23
or if you want to move it or you want to postpone,
46:25
you have different solution.
46:28
If there are different levels that have been moved,
46:31
you can select all of them and tell them
46:35
to move to the right position.
46:38
With that said, let's talk now about linking IFC into Revit.
46:42
You can use the information from Industry Foundation Classes
46:46
files in Revit model when you want
46:48
to collaborate with other non-Revit models
46:51
in an open beam workflow.
46:53
To use IFC files in a Revit model,
46:56
you can either open the IFC you are importing into Revit
47:01
or you can link it.
47:02
You open the IFC file in Revit to create
47:05
a new model that use the IFC data as a starting point.
47:09
So if there are later changes on the IFC,
47:12
they will not be reflected on the Revit model,
47:15
is just imported open at once.
47:17
In that case, is usually recommend
47:20
to link the IFC file to an existing Revit model
47:23
to reference the information for additional design work.
47:27
And the model can be update, the IFC can be update
47:31
and then you just need to reload the IFC
47:33
and the change will be shown, the [INAUDIBLE] change
47:36
will be shown from the new IFC in your [INAUDIBLE]..
47:40
Revit support in different IFC format
47:43
based on the International Alliance for Interoperability.
47:47
These are IFC4, IFC2x3, 2x2 and 2x.
47:54
Before opening or linking an IFC file,
47:57
you can specify the template you want to use from another Revit
48:01
file, you can load a single txt file
48:05
that is used to map the IFC classes to the Revit category.
48:10
And you can manually override the Revit categories
48:13
for IFC classes.
48:15
If you have existing design create using AutoCAD,
48:20
you can import this AutoCAD or any other CAD format
48:24
to the [INAUDIBLE] model.
48:26
However, if the DWG or the CAD is update after [INAUDIBLE]
48:31
imported, now Revit will not automatically
48:34
reflect this change.
48:36
Import CAD files or DWGs, they affect negatively
48:41
to the Revit performance.
48:43
You will not be able to find them
48:45
because they can be copying different view,
48:48
they can even be hidden and you will not
48:50
have an easier way to find it.
48:53
If you import the file, you can always explode the DWG
48:58
to the Revit elements but we strongly
49:01
recommend not to explore DWG files in Revit.
49:04
It is possible but this is really not recommended
49:07
because it will really affect the negatively
49:09
to their performance.
49:10
Consider to import them.
49:12
In that case, if you really want to import an empty link,
49:15
consider the import that on an empty Revit model
49:19
and link it into your own model.
49:21
This last [INAUDIBLE] model.
49:24
It makes [INAUDIBLE] model is clean
49:27
and you can easily handle the visibility of the DWG
49:31
by handling the visibility of the link Revit model.
49:35
So in general, to wrap up here, importing DWGs or CAD file
49:41
is not the recommended option.
49:44
If possible, always link the DWGs.
49:48
So if you have existing design created
49:50
using AutoCAD or other CAD product,
49:54
you can link that into our Revit models.
49:58
Linking CAD files is usually the right approach.
50:01
If you link in the DWG or the CAD file,
50:04
they can easily be updated to reflect
50:07
the changes from the CAD file.
50:10
However, keep in mind that in this case,
50:12
you cannot explode the nest in DWG links to Revit elements.
50:17
Why and when should we link that file in the Revit project?
50:22
Use the CAD file as a starting point for your desire.
50:25
It is common that the project team
50:27
receives documentation within DWDs or AutoCAD
50:31
format resulting from a competition or some
50:35
[INAUDIBLE].
50:36
So you can link these documents into your Revit
50:39
as a starting point to create journal.
50:42
You can use also DWGs or CAD format
50:45
to bring the site plan into your Revit project.
50:49
Civil engineers or landscape architect
50:52
often follow what one documentation in different CAD
50:54
format.
50:55
And this is very useful just to link and get it
50:57
in your [INAUDIBLE].
50:59
You can use CAD format to include 2D details in Revit
51:04
instead of doing the detailing in AutoCAD,
51:06
but you can do it in Revit just by bringing
51:09
these DWGs directly.
51:12
In this case, you can also consider to link PDFs.
51:15
Their appearance will be easier to manage if you bring
51:18
in the detail already as a PDF.
51:22
You can place these links from PDF or DWGs
51:25
on views or directly on drafting views.
51:29
In general, it's very useful to collaborate with partner
51:33
not just working without of color on a project like these.
51:37
You can keep working on Revit and collaborate
51:41
with other stakeholders that they are still working on CAD.
51:46
If you want to bring CAD file into private families,
51:50
you have just the option to import them not to link them
51:54
as you have in Revit file.
51:56
So you might want to clean [INAUDIBLE] CAD files in family
51:60
to include 2D information.
52:02
For example, you want to enrich their appearance
52:04
for the day link and the day component families.
52:07
But if possible, it is recommended always
52:09
to create the geometry in Revit not to import the DWGs.
52:12
You can import maybe the DWG, use it
52:15
as a reference to recreate the lines, the symbol lines,
52:19
and then delete it before loading
52:21
the family on the project.
52:23
That would be ideal.
52:25
So when linking DWG file into Revit project,
52:29
consider to create a specific workset if you are
52:33
working on a work-shared model.
52:35
But consider as well to create a Model-in-Place Family
52:39
and select the right category and link the DWG
52:42
inside this Model-in-Place.
52:44
It allows you to cut the geometry of the CAD file,
52:49
always, of course, if it's loading a category family.
52:52
If it's not linked inside the Model-in-Place family,
52:55
then the DWG will not be [INAUDIBLE]..
52:59
It also helps if you want to get the DWG in the Revit schedule
53:05
as a new element.
53:08
As I was saying in the beginning,
53:10
Revit project and DWG can share coordinates.
53:14
So consider to establish a coordinate between DWG
53:17
and Revit files to ensure a correct position.
53:21
Before linking the DWG file into Revit,
53:24
there are some recommended step you should take into account.
53:27
For example, remove any unnecessary data as layer
53:32
that you are not using, that you don't want
53:34
to bring directly in AutoCAD.
53:37
It will impact positively to the performance.
53:41
Keep the CAD drawing in a small area.
53:43
Do not bring and extend CAD if you cannot not need the whole
53:47
extension of it, also affecting to the performance.
53:51
It is recommend to purge and audit the DWG.
53:54
As we say for Revit before, change the proxy graphics
53:59
variable value to one and export proxy object
54:03
to native AutoCAD object.
54:05
Change all the text at font to a present Revit font.
54:11
Arial, for example, would be an example.
54:13
So make sure that the font that they are showing in AutoCAD
54:16
is included in Revit.
54:18
And finally, bind all XRefs if you
54:22
want them to show up in Revit.
54:25
With that said, we are actually at the last section,
54:27
where we will talk about performance best practices.
54:31
Let's talk about that next.
54:33
Updates provide fixes and new feature
54:36
within the same Revit version.
54:39
Revit user working on the same central model
54:42
must collaborate with in the same Revit version.
54:46
It is not possible otherwise.
54:49
But in addition, it is highly recommend to work in the same
54:52
build and hotfix.
54:54
Apparently, it is possible to work on the same central file
54:59
with different build and hotfix, but it
55:02
is a high potential risk you should not
55:05
take to avoid model corruption.
55:08
You can always have a look for new update your AutoDesk
55:11
Desktop app or go through your AutoDesk portal.
55:16
Let's talk about model groups.
55:17
Model groups are an important point
55:19
to pay special attention if we want to keep a high performance
55:23
model.
55:24
In fact, model groups slow file performance
55:27
and increase the file size considerably.
55:29
I understand we often need to work with model groups.
55:33
But they will advise to remove groups
55:36
as soon as they are no longer needed.
55:38
Do not include any Datum Object into a group
55:42
as levels or grids.
55:44
It is highly recommend as well to include elements
55:47
in a group within the same workset.
55:49
Host element and hosting element should
55:53
be always grouped together.
55:55
Remember that the groups should not
55:57
be a replacement of families.
55:59
Anything you can do with a family
56:01
should be done with family and not
56:03
by grouping different element.
56:05
Use groups only if they are at least
56:08
repeated a minimum of instance.
56:10
The news groups is they are just repeated once or twice.
56:15
It's not recommended to nest group within a group.
56:21
Even if you can think that in some situation
56:24
from preliminary design can be a quick solution and helpful,
56:28
it also generates frustration to access
56:30
to the right information.
56:32
And also, when you want to get out of the group,
56:35
again, difficult because you have to close the group,
56:39
close the next group, and so on.
56:41
Finally, do not mirror groups.
56:44
It might work, apparently, in Revit but not in real life.
56:48
So better always to create a right and a left version.
56:52
So for example in equipment usually,
56:54
they do not exist on a mirror version.
56:57
Or if you mirror a door or a group containing a door,
57:01
the swing information of the door will probably be false.
57:07
Let's talk about rooms and space.
57:10
Rooms and space are also affecting
57:12
to the model performance.
57:14
It's convenient only to check the Room Bounding
57:17
option for the link file if it's absolutely necessary.
57:21
If the file is not affected to the new bounding option,
57:25
it should not be selected.
57:27
So Select the link, Edit Type, uncheck the Room Bounding.
57:31
You see here.
57:33
That's by selecting the type and edit it.
57:36
You should unselect the Room Bounding
57:38
if the link is not affecting to the calculation of the room.
57:43
If your model has a warning about overlapping room
57:46
boundaries, this is one of the Warning
57:49
that you should resolve as soon as possible.
57:52
It is affecting the performance of the model,
57:54
but it's also affecting the accuracy of your model.
57:58
So consider to place a room separation
58:00
line on a specific workset for better control.
58:04
You can prepare, as we say before, a 3D view just
58:08
showing this specific workset.
58:10
Unlike this, you can control all the room
58:12
separation line if they are set in the right workset.
58:16
Try to avoid overlapping between room
58:19
or a space separation line between themselves, but as well
58:23
with walls.
58:24
You will get also warning about it
58:26
and is one of the priority one you should take out.
58:31
And finally, Volume Computation should be enabled just
58:35
when really is needed.
58:37
It's taking a lot of resources off the performance.
58:41
And you can see it here, Area and Volume Computation,
58:46
in general, if it's not needed, area, volumes,
58:50
I recommend that you are working only with areas and not
58:55
with volumes.
58:57
Configure project view to optimize Revit performance.
59:01
The setup of the view will also affect the performance
59:04
of your Revit model.
59:05
Specify a simple drafting view as a starting view
59:09
for your Revit project.
59:11
It will help you to improve the performance
59:13
when opening the project.
59:14
Revit will take less resources to open a simple view
59:19
than to recreate a 3D complex geometry that maybe you don't
59:23
need to access at that point.
59:25
You can also use section boxes to limit the visible geometry
59:29
in 3D views.
59:31
So Revit does not need to calculate the whole geometry
59:33
of your project if you are only working on a specific area.
59:37
Avoid to use the common permanently hiding
59:42
elements in view.
59:43
Turn off the categories that you don't need on the visibility
59:48
graphic or in the view templates and assign the right level
59:52
of detail to this view.
59:55
It will take less resources to calculate
59:58
the geometry and the view itself.
60:01
When working with many views that you are not using,
60:05
it's recommended that you close open views.
60:08
It will take less resources than having all views open
60:12
at the same time.
60:13
We often create work in progress view no longer needed.
60:18
It's convenient to minimize the number of them in your project.
60:21
So regularly, try to delete unused views.
60:25
When you use the Paste Aligned tool to views
60:27
that they are closed, the target views
60:30
will open and close automatically.
60:33
You can improve the performance of this common Paste Aligned
60:37
by opening first all the targeted views
60:40
before the operation of Pasting Aligned.
60:44
Minimize the view depth when it's possible in elevation,
60:49
in plans, or section views.
60:51
Revit will take less resource to recreate the geometry
60:54
since there is less quantity of object to calculate
60:58
in the background.
60:59
Even if they are hidden, this element by another element,
61:02
it takes less resources.
61:05
So for the same purpose, you can also
61:07
consider back clipping views to reduce the quantity of geometry
61:11
maintained on these view.
