Hi.
00:11
My name is Simon Jones.
00:12
I'm an independent BIM consultant,
00:14
and today I'm going to give you an introduction on how
00:16
to use Navisworks on infrastructure projects.
00:19
This Safe Harbor Statement is a legal disclaimer
00:22
that boils down to this.
00:23
Please don't make purchasing decisions
00:25
based on any speculative comments made
00:27
in this presentation regarding possible future changes
00:31
or new features.
00:33
My name is Simon Jones.
00:34
I worked for Autodesk for 35 years,
00:36
where I had a variety of roles for product support, product
00:39
development, technical sales, and consulting.
00:42
I left at the start of 2021, and I'm now an independent BIM
00:45
consultant.
00:47
I've been working with Navisworks since well
00:48
before it was acquired from Autodesk, when it
00:51
was an independent application.
00:52
I'm based near Guildford in the UK.
00:55
Autodesk Accelerators are designed
00:57
to help your team stay ahead of the curve with the latest
00:59
workflows.
01:00
They include courses, videos, and live coaching, which
01:03
is what we're doing today.
01:05
You can see a full list of topics on the Customer Success
01:08
Hub.
01:09
Navisworks can combine separate models
01:11
from different disciplines into a single lightweight,
01:13
multi-discipline model.
01:15
Navisworks can import models from many different products
01:18
and file formats.
01:19
These include all sketch products,
01:21
such as AutoCAD, Revit, Civil
01:25
as [INAUDIBLE] sketch products, such as MicroStation DGN, IFC,
01:29
and SketchUp files, to name a few.
01:31
The resultant model is lightweight and easy
01:33
to navigate around, making it ideal to share
01:36
with an extended design team and support a design review
01:39
meeting.
01:40
A typical workflow for working with Navisworks
01:43
on infrastructure projects has the following main steps.
01:46
First, we export the models from Civil 3D
01:49
as a Navisworks NWC file.
01:52
In this example, we shall be focusing on Civil 3D.
01:54
But in many infrastructure projects,
01:56
there are likely to be a mix of other products,
01:58
such as Revit for building models, on the site.
02:01
And the same principles broadly apply.
02:04
Separate discipline-specific models
02:06
can be combined together in Navisworks
02:08
as a single coordinated multi-discipline model.
02:11
This model can then be used to perform a virtual review
02:13
to demonstrate intent, present progress, and capture
02:16
design issues.
02:17
Issues can be exported as reports to the design team
02:20
to be addressed, and updated models
02:22
can refresh the Navisworks models to tracking resolutions.
02:25
Finally, the model can be published and archived
02:27
as an accurate record of the design
02:29
at any stage of the project.
02:32
This Accelerator provides a quick overview
02:34
of using Navisworks on infrastructure projects.
02:36
The workflow will be based on a roadway and bridge development
02:39
designed in Civil 3D.
02:41
The main topics and overall learning objectives
02:44
we will be covering today are as follows.
02:46
First, we shall learn how to export
02:48
discipline-specific models from Civil 3D.
02:51
Then we shall aggregate the discipline-specific models
02:53
into a single coordinated multi-discipline model
02:56
in Navisworks.
02:57
Before starting the review, we shall learn some Navisworks
02:59
good practices in setting up orientations using Search Sets,
03:03
in order to make the review process as efficient
03:06
and streamlined as possible.
03:07
Once the Navis model has been set up,
03:10
we learn how to navigate around it
03:11
from a virtual tour of the site.
03:14
We shall learn how to take measurements of the model
03:16
and capture those as redline mark-ups
03:18
in annotated viewpoints.
03:20
We shall also see how the model can be used for clash detection
03:23
in order to find interferences between the disciplines,
03:25
as well as how to create a construction sequence.
03:28
We shall learn how to export reports and publish the model
03:31
to report back issues to the design team.
03:34
And, finally, we shall use SwitchBack
03:36
to identify an object in the Civil 3D model
03:38
and demonstrate how to make a change
03:40
and then refresh the Navisworks model.
03:42
Not all the features of Navisworks,
03:44
nor is this a detailed class.
03:46
Instead, this Accelerator is intended
03:49
as an introduction to using Navisworks
03:51
on infrastructure projects.
03:53
Additional links will be provided
03:54
at the end of the webinar if you wish to investigate Navisworks
03:57
further.
03:58
This Accelerator consists of single delivery session
04:01
with an overall delivery time of around 45 to 60 minutes.
04:04
And all products in this presentation
04:06
are utilizing the 2022 versions.
04:10
Let's take a look at how we can export the NWC
04:12
files from Civil 3D.
04:15
When exporting a Navisworks file from AutoCAD,
04:17
the visible entities will be the ones exported.
04:20
So entities with frozen or off layers will not be exported.
04:24
In Civil 3D, they are objects you would not
04:26
want in an a Navisworks model.
04:27
So simply freeze their layers.
04:30
Then, before performing the export,
04:31
I would recommend that you save a 3D view with a name
04:34
such as Navisworks Export.
04:36
And ensure that the Save Layer Snapshot option is enabled,
04:40
so that you could restore to save status any time.
04:44
The NWOPT command in AutoCAD opens the Navisworks Options
04:47
Editor to DWG files.
04:49
Within this dialog, you can fine-tune
04:51
how AutoCAD objects converted.
04:53
In most cases, default settings will be fine.
04:56
But take time to familiarize yourself with these settings.
04:59
To export the model, enter the NWCOUT command
05:03
and select a folder to write the Navisworks NWC file to.
05:08
In order to avoid superfluous geometries,
05:10
we're going to set up a view in Civil 3D
05:12
that has just the relevant geometry.
05:14
In this example, to export just electrical pylons,
05:17
we shall first create an AutoCAD view
05:19
that saves current viewpoint as a layer snapshot.
05:22
So we're going to call this one All 3D,
05:24
and we're going to check Save Layer Snapshot With View.
05:28
And set it as current.
05:31
Next, we're going to use the layer freeze tool
05:34
and freeze the geometry we don't want to see.
05:36
So these surfaces, and these lines,
05:39
so that all we're left with is those electrical pylons.
05:48
Once we have the view and the objects we want,
05:51
we're going to save this as another view.
05:53
Go into the View Manager, and this time we're
05:57
going to call it Navisworks Export, or something like that.
06:02
As people know, this is the one we export our models from.
06:06
And, again, make sure Save Layer is on.
06:14
With two views now set up, you can always go back to a working
06:18
view-- there's our All 3D--
06:19
as we were at the beginning of the process.
06:24
Or we can quickly go back to the Navisworks Export, which
06:28
has the objects we have in the model that we want to export.
06:32
And once we're happy with that, we run the NWCOUT command,
06:36
specify name, and save it to our hard disk.
06:43
Notes.
06:43
You can open AutoCAD DWG files, as well as many other file
06:46
formats, directly in Navisworks, and it'll
06:49
be automatically converted into a Navisworks NWC file.
06:52
Whilst this can be part of a successful workflow,
06:55
there are two issues to consider.
06:57
Firstly, it is less obvious which
06:59
geometry will be included.
07:01
In the AutoCAD export option, what-you-see-is-what-you-get
07:04
approach is far more predictable.
07:06
Also, when importing DWG files from Civil 3D
07:10
as opposed to standard AutoCAD, the relevant Object Enablers
07:13
need to be installed on a machine
07:15
running Navisworks works in order
07:17
to read non-standard AutoCAD objects, such as TIN surfaces.
07:21
We shall now take a look at how to aggregate
07:23
the discipline-specific models into a single federated
07:26
multi-discipline Navisworks model.
07:29
Typically, the federated model is
07:31
created by a model coordinator, who could, for example, work
07:34
for a general contractor.
07:35
Their role will be to create a coordinated multi-discipline
07:38
model that can be reviewed by members of the extended design
07:41
team, subcontractors, or client representatives.
07:44
As previously mentioned, the design models
07:46
can be a combination of different file formats,
07:48
such as AutoCAD DWG, IFC, and Revit RVT.
07:53
Whenever are these files are read indirectly or exported
07:56
from design applications, Navisworks imports the data
07:59
as an NWC file, which stands for Navisworks Cache.
08:03
When the NWC files are read into Navisworks,
08:06
the file could be saved as an NWF file.
08:09
This stands for Navisworks File Set.
08:12
This is a live file that simply references
08:14
the discipline-specific geometry and metadata
08:17
from the design application saved in the NWC files.
08:21
If the underlying NWC files are updated,
08:23
the updates are reflected in the NWF file,
08:26
enabling an iterative review and update of the design.
08:29
The NWF also stores Navisworks-specific data,
08:33
such as annotated viewpoints and comments that will
08:36
be explained in this session.
08:37
At any point, the data can be encapsulated
08:39
into a single NWD file, which stands for Navisworks Document.
08:44
But perhaps Navisworks Distributable
08:46
would be a better name.
08:48
An NWD file is much like a ZIP file that
08:50
contains all the design geometry and the metadata,
08:53
as well as the Navisworks-specific
08:55
data, such as the annotated viewpoints and comments.
08:58
Whilst an NWD file has lost its ability
09:01
to update the changes to the NWC files,
09:04
it does mean it is ideal for archiving a state of the model
09:07
with all the associated design review
09:09
information for future reference.
09:10
Not only that, an NWD file can be viewed free by anyone
09:14
using the Navisworks Freedom viewer.
09:17
In order to create a federated Navisworks model,
09:20
we're going to start by opening one of the NWC files.
09:23
In this case, we're going to open the electrical file.
09:26
And we're not seeing any geometry,
09:27
so we're going to pick on the Viewpoint that
09:29
was imported to Navisworks Export
09:31
to align ourselves with the view we had inside AutoCAD.
09:35
Additional files can then be appended to this.
09:39
So we're going to start off with the water, storm water,
09:41
and sewage water piping systems.
09:44
Add those into our model, and see those in place now.
09:50
Next, we will append some more files.
09:54
In this case, we're going to go for the bridge--
09:58
there it appears in the middle--
09:60
and, finally, we'll add in the road itself.
10:04
Now, before we get lost let's zoom out
10:07
and save the current Viewpoint as a home view.
10:22
Do this from the Viewpoint ribbon.
10:23
Save Viewpoint, and we're going to call it Home.
10:28
This way, if we get disorientated,
10:30
we can always come back to a set place.
10:39
Next, we're going to replace the black background
10:41
with a graduated blue background.
10:51
And this would be a good time to save our progress.
10:54
This now is going to save as an NWF file.
10:59
I'm going to call it Infrastructure Intro.
11:01
So these NWC files you see in the selection tree are just
11:05
being referenced in.
11:06
And any changes to those files will update this model directly
11:09
when they're reloaded.
11:11
Key to running a successful model
11:12
review is to set up some viewpoints that
11:14
will enable you to quickly jump to areas of interest.
11:18
This is especially useful if you have a large audience
11:20
in the design review, to avoid time being wasted
11:22
during a meeting wandering aimlessly
11:24
around the virtual world.
11:27
Before setting up any viewpoints,
11:29
it's worth making some changes to some global settings.
11:32
If you open up the Options Editor
11:34
and navigate down to the Viewpoint Defaults,
11:38
you'll find three settings.
11:39
Save Hide And Required Attributes,
11:42
Override Appearance, and Override Linear Speed.
11:45
By default, these are all unchecked.
11:47
I would recommend that you check all three of these options.
11:51
It's a global setting, so once it's done once,
11:54
it'll be saved for future use.
11:56
Secondly, you scroll down a bit further in the Options Editor,
11:59
come to Model, and in Performance, you'll
12:01
see there's an option called Close NWC/NWD Files On Load.
12:05
Likewise, this is off by default.
12:07
I always switch this on.
12:09
And what this means is you're able to overwrite a loaded NWC
12:14
file.
12:15
So you don't have to unload it if you make changes to update
12:17
your model in a live session.
12:20
Once again, it's a global setting.
12:21
Only needs to be done once.
12:24
When displaying objects, the color
12:25
is determined by the design application.
12:28
In the case of Civil
12:30
be displayed based on its CAD color, which can result
12:32
in a confusing array of colors.
12:34
Good practice is to set up a color standard
12:37
so certain objects consistently display
12:39
in the same color across different projects,
12:41
so that they are easier to identify.
12:44
For example, you may want to display
12:45
precast concrete in light gray.
12:48
Structural steel could be in oxide red,
12:50
and mains water pipes could be light blue.
12:53
Navisworks includes a tool called the Appearance Profiler
12:56
that applies color overrides to objects based on properties
12:59
that identify them.
13:00
The configuration could be saved as a DAT file
13:02
for sharing between projects to support standardization.
13:06
Let's flip the model over and take a look at the below ground
13:09
surfaces.
13:11
Notice that two of the pipe systems
13:13
are blue, which is the color used in Civil 3D
13:15
AutoCAD to highlight objects.
13:18
So when we highlight an object, if it's blue, we don't see it.
13:22
We see the purple one.
13:23
We could see the blue one-- we can't.
13:25
So this is a good example of why we'd
13:27
want to override these colors.
13:28
We can't, also, tell the difference
13:30
between what pipes they are.
13:33
So we could take an individual pipe, like that one,
13:35
and override it and display it in yellow.
13:38
But this would be pretty tedious if we
13:40
were to go around the whole bottle recovering our pipes.
13:45
So what we're going to do is we've
13:46
created some search sets, which I'll explain in
13:48
more detail later, that highlights or finds
13:50
all the pipes on a certain system, in this case, sewage.
13:56
And for this, we're going to override its color
13:58
and make those yellow.
14:03
And we're going to repeat that process for water.
14:07
And this search finds all the water pipes and these ones
14:11
we're going to make light blue.
14:19
And for the storm water, we're going to make those orange.
14:26
Now we can easily identify our water, our sewage,
14:29
and our storm water pipes based on their color.
14:31
If you use the same colors consistently,
14:33
you always know which is which.
14:35
Now when I select that object, it is not blue anymore.
14:38
It's yellow, and it's easier to see.
14:43
Now, if we return to the normal colors,
14:45
we reset all appearances and we go back to the original colors,
14:48
blue and purple, we can show you another way
14:50
of doing this using the Appearance Profiler.
14:55
Here we're going to select the sets,
14:57
and we're going to apply the same colors in here.
15:02
So we're going to do it.
15:03
This could be good for many objects.
15:04
We're just doing these three sets of pipes.
15:06
So we're going to go to the sewage, the water,
15:08
and the storm water with the same colors.
15:13
Well, what we can do is we can save this as this DAT file
15:17
so that we can open it in another project and reuse it.
15:19
Simply hit Run, and the pipes on those systems
15:23
will get the color that's been assigned by the Appearance
15:26
Profiler.
15:30
Before we start a review, it's important to set up
15:33
some orientation viewpoints.
15:35
On large, complex sites, it's quite possible
15:38
to get lost in the 3D world.
15:39
For this reason, it's advisable to set up
15:41
these pre-defined viewpoints that you can instantly
15:44
relocate to.
15:46
First, review any views that aren't imported from the design
15:48
files, and consider moving relevant ones into an imported
15:51
folder and deleting any irrelevant ones.
15:54
Each view can save numerous properties and not
15:57
just a view direction.
15:58
They can also save the render style, which
15:60
sets whether the view is displaying materials or object
16:03
colors, the view projection that is
16:05
either prospective or orthographic,
16:07
the objects that are visible in the view and those that
16:09
are not, transparency state of objects,
16:12
the navigation mode, which sets whether you are pre-set set
16:15
to walk, fly, or orbit, as well as a default walking
16:18
or fly speed.
16:19
This is handy, as you would want to set a speed that is
16:22
appropriate for the location.
16:23
For example, within a room of a building,
16:26
the default of about four meters per second would be fine.
16:29
But flying across a large site, such as this one,
16:31
it would be too slow.
16:32
With this in mind, it's worth setting up
16:34
a series of views that will enable the model
16:36
coordinator or other team members
16:37
to efficiently review the design.
16:40
Here we have a number of views set up.
16:42
And in the Saved Viewpoints list,
16:43
we've created a couple of folders,
16:45
one for the imported views and one for some orientation views.
16:48
We started off with a bird's eye view,
16:50
flying in across the road at a default
16:53
speed of 4 meters per second.
16:55
As you can see, this would take forever to reach our bridge.
17:01
So I've set up a different view.
17:04
This one has got a fast speed at 100 meters per second,
17:06
which is far more appropriate if you're flying around like this.
17:10
You can crash.
17:12
I'm going to reorientate ourselves with an
17:14
Under the Bridge view.
17:18
And from this, we can walk around,
17:21
and I can use my mouse to look up and down.
17:25
And I can use the Realism modes to switch on Collision
17:28
and Gravity so that I can walk up the embankment
17:31
and I stay with my feet firmly on the ground.
17:34
If I use my mouse wheel, I can pan around,
17:36
and I can look up and down.
17:38
Now looking underneath the road, and we've
17:40
got Gravity switched off, because we wouldn't
17:42
want to fall down to eternity.
17:43
So we can wander around, walking around the piles,
17:47
checking the design without falling down.
17:56
Back on top of the road, I'm walking around.
17:58
But in this case, the road has had its transparency
18:03
set so that we can see the pipe runs underneath the road
18:07
surface as we're walking around.
18:09
So we can check the pipe design through the road.
18:12
So in some review ports, a powerful way
18:15
of setting up the model for an efficient review in a far
18:17
more than simply Save View directions
18:20
There are two main render styles that control
18:22
how Navisworks display objects.
18:25
The Shaded option displays objects using their color
18:27
and transparency setting, whereas the Full Render option
18:30
displays objects using materials, such as concrete,
18:33
brick, or grass, which will override the color
18:36
and transparency settings.
18:38
Should you wish to generate renders with even more realism,
18:41
Navisworks include a Ray Trace render
18:43
that will provide enhanced lighting and material control.
18:46
Whilst this is not as fast as a standard renderer,
18:49
there is an option to have the renders generated
18:51
in the cloud, which is significantly faster
18:54
and doesn't tie up a desktop machine.
18:56
The View Section feature enables you to slice through the model
18:59
in order to cut away nonrelevant geometry
19:02
or view hidden features, such as cross section
19:04
the structural composition of the bridge.
19:06
You can define single cut plains or, in the case of the example
19:10
on the slide, a box section that can isolate
19:12
an area of the model defined by a rectangular box
19:14
with four sides, a top, and a bottom.
19:18
To make a sectional view, we start
19:20
with entering the Enabling Sections
19:22
and picking the section mode we want to use.
19:24
We're going to use a Box.
19:27
And here we're using the Scale gizmo to move it around.
19:31
And here we can look up from above.
19:33
And we're going to use the Rotate option to rotate it
19:36
and line it up with our bridge.
19:37
Then we're going to move it in position,
19:41
and orbit back again, and scale it one more time.
19:49
So we cut away the area around the bridge,
19:51
and now we've got a nice, neat bridge we can look at.
19:54
We can pick on one of the items, or use
19:57
the Swivel to spin around our bridge without having
20:01
all the rest of the road to worry about,
20:03
and just cut away the area of interest,
20:05
which is just this bridge area, using that Section box.
20:08
This can be saved as a Viewpoint, which
20:10
we'll call Bridge Section.
20:11
And any time, we can jump between this
20:15
or any other Viewpoint, and the current section
20:17
will be remembered with that Viewpoint.
20:20
Selection and Search Sets are a powerful feature
20:23
for grouping together objects and they're
20:25
used as an essential skill for working
20:26
efficiently with Navisworks.
20:29
Use Selection Sets and Search Sets to group together items
20:32
for re-selection.
20:33
Selection Sets are named static groups
20:36
of items based on a manual selection,
20:38
whereas Search Sets are named dynamic groups of items
20:41
based on search criteria, which update automatically
20:44
as the model changes.
20:46
You can export Search Sets to XML files
20:49
for re-use across projects.
20:51
In this example, we shall use the Box selection
20:53
mode to create a Selection Set of just the roundabout objects.
20:58
We'll save this selection and call it Roundabout.
21:01
And then we're going to use Hide Unselected
21:03
so nothing else is visible other than the roundabout.
21:05
There you see we can select it again,
21:11
or we can come and select our Piles.
21:14
Here, we see our Piles are on a layer called Foundations.
21:18
So we're going to now create a Search Set called Foundations,
21:22
which is going to find all items which have a layer called
21:24
Foundations.
21:26
Or we can change the search criteria to Piers
21:31
and run the Find All, and we will
21:32
find all of the items that are on the Piers layer.
21:38
And we're going to call that Piers.
21:39
So now we've got two Search Sets, one called Foundations
21:42
and one called Piers.
21:43
We're going to place those in a folder called Structure.
21:47
And we can group them together.
21:48
We can drag these Search Sets into the folder.
21:57
And as we pick on those, you highlight the objects,
21:59
or we pick on the folder and it highlights all the objects
22:01
within those.
22:03
And we can even use Invert Selection to select
22:05
everything but our items.
22:08
In this case, we're going to make
22:09
everything else transparent, so if we
22:12
want to see our structure underneath our bridge
22:15
in context.
22:21
Once the Navisworks model has been prepared with Viewpoints
22:23
and Search Sets, it is ready to support the model review
22:26
process.
22:28
A necessary part of the model review
22:29
is to move around the model, and Navisworks provides three
22:32
different navigation options.
22:34
Which you use will be down to personal preference
22:37
and some subtle differences.
22:38
Originally, Navisworks included just the Navigation Bar,
22:42
with options such as Zoom, Pan, Orbit, Fly, and Walk.
22:46
However, once the product was acquired by Autodesk,
22:49
the Steering Wheel and ViewCube were also
22:51
included to provide a consistent 3D navigation
22:54
experience across the suite of Autodesk products.
22:57
Familiarize yourself with all three options,
22:60
as they all have their advantages.
23:02
The Measure tools can be used for measuring distances, areas,
23:06
and angles of the model geometry.
23:08
A neat feature is the option to measure the shortest
23:10
distance between two objects.
23:12
And if, for example, you just need the vertical distance,
23:15
you can enable the Lock feature to constrain the measurement
23:18
to just the z-axis.
23:20
Initially, measurements are displayed temporarily
23:23
on the view, but they can be converted into redlines
23:26
and saved to a viewpoint.
23:29
The Navisworks redlining tools are fairly basic.
23:31
But that does make them very easy to use,
23:34
and it will not take long to get familiar
23:35
with the tools, such as Cloud Ellipse, Arrow, and Text.
23:39
Once the redline is placed, it is automatically
23:42
added to the current view, or a new view
23:44
is created, if required.
23:46
Redlines disappear when you navigate away
23:48
from the viewpoint, but reappear when
23:50
the viewpoint is returned to.
23:52
In this demonstration, which starts with a Home view
23:55
and which we use with ViewCube to adjust the view direction,
23:58
the advantage being that we get a nominal compass
24:01
so we know which way we're pointing.
24:02
And we can use this to drag around.
24:08
Or I can switch to the Steering Wheel.
24:11
And I could go into a Walk mode, and I
24:14
can use this Steering Wheel to change it into an up-down mode
24:17
so it's all interactive on the screen.
24:20
Or I can use the back into Walk mode again, look down a bit,
24:27
move myself down, go back into Walk, all in one control.
24:37
Now I'm at my guardrail.
24:38
I actually want to see the height of this guardrail.
24:41
So I'm going to go to the Measure tools,
24:43
select the Point to Point option,
24:46
and I'm going to have the z-axis locked.
24:49
And I'm going to snap to the edges,
24:53
and I'm going to measure the vertical distance
24:55
between the bottom of the rails and the top.
24:57
As you can see, it's 0.8 of a meter.
24:60
And then I'm going to convert this to a redline.
25:02
And when I do this, it automatically
25:04
creates a new view, just called View,
25:06
which I'm now going to rename to Guardrail Height.
25:11
And I'm going to start a new folder called
25:15
Project Review, or Model Review, and today's date.
25:19
And I'm going to place my Guardrail Height
25:22
annotation into that folder.
25:25
Let's go off and have a look under the bridge.
25:30
I can look up and down with my mouse wheel.
25:33
And in this case, I want to measure
25:34
the distance between the road and the bottom of the bridge
25:37
to work out the clearance.
25:38
So I'm going to pick the two items.
25:40
With two items picked, I can use the Shortest Distance tool.
25:44
And it tells me there's 7.2 meters
25:46
from the road to the bottom of the bridge,
25:48
which, again, I convert to a redline.
25:50
That creates a view, which I'm going
25:52
to rename Bridge Clearance, and drag that view into my folder
25:57
for my Model Review.
26:02
Let's get back into Walk mode, and we're
26:06
going to wander around our road.
26:08
We're going to look for more things to inspect.
26:12
And first thing I notice, this lamppost
26:15
seems to be flying up in the air.
26:18
So we're going to get ourselves a good view of it.
26:25
And if I select it and look at its properties,
26:27
we can see that it's point number five.
26:29
That could be useful.
26:30
So I'm going to copy this information into the Clipboard,
26:33
that it's lamppost number five.
26:37
I'm going to go to the Cloud tool,
26:39
and I'm just going to quickly put a cloud around the area
26:42
and put an arrow in indicating that this lamppost really
26:47
should be down there somewhere.
26:49
And I'm going to add a little bit of text,
26:51
as well, to highlight the floating lamppost.
26:56
This, too, has created a view, which I'm going to rename to--
27:00
well, I'm going to add a Comment, first of all.
27:03
The comment is going to be that we've got a floating lamppost,
27:07
and I'm going to add the information on the point
27:09
number, since it could be useful to someone.
27:15
And this view we're going to rename Floating Lamppost,
27:18
and drag that into our Model Review.
27:20
You could have lots and lots of views in here
27:22
after a review meeting.
27:23
But I can now quickly jump between all of these views
27:26
and get a quick summary of all the issues I found
27:28
during our project review.
27:32
The Clash Detection feature in Navisworks Manage
27:34
will then analyze the model and report on interferences
27:37
between objects so that the design can
27:39
be rectified and avoid costly on-site resolutions.
27:43
Key to effective Clash Detection is not
27:45
to try and clash everything against everything,
27:47
but to focus on what items have the highest priority,
27:50
in terms of impact and time constraints.
27:53
An example of high-priority clash
27:55
is one involving foundations and underground drainage systems.
27:58
These items have high time-based priority,
28:01
since they're the earliest part of the construction.
28:03
And foundations have high priority relating
28:05
to clash resolution, in that moving foundations would have
28:08
a serious impact on the integrity of the structure,
28:11
and there would be significant repercussions
28:14
if they were moved or changed.
28:15
Furthermore, drainage systems that run on a fall cannot
28:18
simply be rerouted over or around an obstacle,
28:21
such as foundations.
28:23
Individual clashes can be assigned
28:25
to whoever needs to provide the resolution,
28:27
along with a status for tracking the progress.
28:30
And there's even a possibility to simulate clashes
28:32
with moving objects over a period of time, such as cranes
28:36
and other plant equipment.
28:38
In this example, we shall set up a clash test
28:40
to check the interference between bridge
28:42
foundations and the underground pipe systems.
28:48
So we've got the Search Sets set up to identify these objects.
28:51
And we'll open up the Clash Detection panel.
28:56
And we're going to add a test, where for the test name,
29:02
we're going to say it's Foundations versus Pipes.
29:05
And in the Selections, we're going to select our Sets.
29:09
So we're going to set the Foundations on one side,
29:11
and we're going to compare this with the Below Ground Services.
29:15
And we're going to pick the folder, which
29:17
is going to be for all services, Sewage Water, Water,
29:21
and Storm Water.
29:22
And we're going to run a test.
29:24
From that test, we can see we found
29:26
a single clash of a pipe running through our piles
29:29
underneath our bridge.
29:31
Notice how the piles are in red, pipes are in green,
29:34
and the rest of the model has been grayed out
29:37
so we can see it.
29:39
Now we're going to assign this to the drainage engineer
29:42
and ask him to reroute the pipe around the foundations.
29:48
We can set up a number of tests.
29:51
So we're going to add another test.
29:53
This time, we're going to actually check and make
29:54
sure our pipes are not intersecting with other pipes.
29:56
So we could do Pipes versus Pipes.
30:02
So for this, we're going to say all the Below Ground
30:04
Services against all the Below Ground Services.
30:08
And we're going to run the test.
30:11
This, however, has reported 79 clashes,
30:15
which is a lot to deal with.
30:20
If we look at these, we'll find, actually, a lot
30:22
of these clashes are where the pipes are actually
30:25
connecting into their concrete inspection chambers,
30:28
and things like that.
30:29
So they're not actually clashes, so we can ignore those.
30:32
So we're going to set up a couple of rules.
30:34
The one we're going to do is say it's not a clash
30:36
if it appears in the same file.
30:38
The little yellow triangle tells us this clash test is invalid.
30:44
So we'll now reset it, remove all the clashes,
30:47
and we're going to rerun that test.
30:52
This time, we only end up with one clash.
30:55
Here, we see we have a water pipe running through a sewage
30:58
manhole, which sounds a fairly high-priority one to fix.
31:02
So we're going to assign this one to the water engineer.
31:08
And we'll ask him to reroute his pipe around a manhole.
31:15
Once we've done the clash tests, we
31:17
have a number of ways of reporting the results.
31:23
First up, we're going to use the HTML Tabular report.
31:27
We're going to write a report, and it
31:29
writes as an HTML file, which can be seen as such.
31:33
So you see those two clashes we found
31:35
and all the information about them
31:36
and who they're assigned to.
31:38
The HTML file can also be read in Excel.
31:42
And here we see it as an Excel file,
31:43
which, again, can be just emailed off to the design team
31:46
to fix.
31:48
Alternatively, we could save the report as viewpoints.
31:53
So when we write this report, we end up
31:56
in the Save Viewpoints list as some viewpoints
31:59
of each of the clashes.
31:60
So there's clash one, of the foundations with the pipe,
32:03
and here's the clash of the pipe going
32:04
through the manhole cover.
32:07
So we can inspect them in context
32:09
of the rest of the model.
32:11
The Navisworks TimeLiner feature can
32:13
be used to create
32:15
such as construction sequences, that
32:18
can animate a virtual construction based on a project
32:21
schedule.
32:22
Items in the model can be linked to a task schedule linked
32:25
to a project plan, which can be developed within Navisworks
32:28
or imported from planning applications,
32:31
such as Microsoft Projects or Primavera P6.
32:35
The task hierarchy is displayed clearly as a Gantt shot
32:38
within the TimeLiner panel.
32:40
The simulation can represent items being constructed,
32:43
demolished, or temporary works.
32:45
It is even possible to have items
32:47
moved during the simulation to represent plant movements,
32:50
such as cranes turning.
32:52
Once generated, the simulation can
32:54
be exported and shared as a video file
32:56
or replayed within Navisworks.
32:59
Here we see the bridge with the TimeLiner module.
33:02
Included with the model is a pile driver
33:04
that we should include in our construction simulation.
33:09
The task list has a hierarchy that
33:11
has main tasks and subtasks.
33:14
We can develop this list directly inside the Navisworks
33:17
panel we've got here.
33:22
Or we can switch to the Data Sources tab
33:24
and import these from products like Microsoft
33:27
Projects and Primavera P6.
33:31
Each of these tasks can be assigned start and end dates.
33:37
We can assign task types, such as whether they're
33:41
construction, demolition, or temporary tasks.
33:45
We can assign the objects associated with those tasks.
33:51
And we can even assign whether or not
33:53
there's an animation associated.
33:55
So each of the pile driver tasks we've
33:58
assigned an animation that will drive the pile
34:01
driver across the piles.
34:08
To run the simulation, we switch to the Simulation tab and hit
34:12
Play.
34:13
And the simulation will play out across the screen.
34:16
And in the viewpoint, we'll see the state of the model
34:19
on any particular day.
34:20
At any point, we can stop it, inspect the project progress
34:24
for any given day, and then continue until the construction
34:27
sequence is complete.
34:28
And here we see the final completed construction sequence
34:32
after day 42, or week six, of our simulated construction.
34:37
Once the model has been completed,
34:38
it is necessary to report the findings
34:40
with whoever needs to know.
34:41
This is most likely to be project managers, discipline
34:44
leads, and a design team, but may also
34:46
include the client, who simply wants
34:48
to have an overview of the project progress.
34:51
Annotated views can be exported as a simple image,
34:54
or all the mark-ups and comments attached to viewpoints
34:56
can be written to a Viewpoint Report
34:59
in HTML format, which includes viewpoint thumbnails.
35:02
Earlier, we already saw how Navisworks
35:05
generates clash reports and explained
35:07
how 4D construction sequences could
35:09
be exported as video files.
35:11
However, the most powerful option
35:12
is to publish the review to an NWD file that encapsulates
35:16
all the information, including the actual state of the review
35:19
design and all viewpoints, comments, and mark-ups.
35:23
An NWD is a single file much like a ZIP file
35:26
that includes all the model geometry and the Navisworks
35:29
information as a snapshot.
35:31
In this case, updates to the original NWC cache files
35:35
will not update the NWD file, making
35:38
it ideal for accurate record of the model for a given date.
35:42
Furthermore, the NWD file can be viewed, but not edited,
35:46
by anyone using the free viewer, called Navisworks Freedom,
35:49
enabling anyone access to the information.
35:52
However, in the case of sensitive information,
35:55
an NWD file can also be password protected
35:58
to protect its confidentiality, or given an expiry date so
36:01
that it is not inadvertently referenced
36:04
after it is considered to be out of date information.
36:07
SwitchBack enables you to select an object in Navisworks
36:10
and then locate and zoom into the same object
36:13
in the originating design applications, such as Civil 3D
36:16
in this example.
36:18
The native CAD package must be installed
36:20
and running on the same machine as Navisworks for SwitchBack
36:23
to work.
36:24
And, in the case of AutoCAD, it is
36:26
necessary to first run the NWLOAD command
36:28
to load the NW Export plug-in so that it
36:31
is primed for the SwitchBack.
36:33
To perform a SwitchBack, locate an item in Navisworks
36:36
and select the SwitchBack option from the Item menu.
36:40
AutoCAD will then attempt to locate the equivalent AutoCAD
36:42
entity in Civil
36:45
Back in the floating lamppost view, we select the lamppost
36:49
and then select SwitchBack from the menu.
36:51
Over in Civil 3D that is running on the same machine,
36:54
the equivalent lamppost has been identified and selected.
36:57
In this example, we shall simply use the Move gizmo
36:60
to drag the lamppost down to approximately
37:02
the right elevation.
37:04
We shall then re-export the model using the NWCOUT command
37:08
to write a new NWC file and override the existing one.
37:15
Back in Navisworks, we can simply
37:16
select the Refresh tool to reload the updated NWC file
37:20
and the lamppost will drop down to the right position.
37:24
Now that we are happy the issue has been fixed,
37:26
we shall edit the Comment on the viewpoint
37:28
and change its status to resolved.
37:38
Hopefully this session has provided a good overview
37:40
of using Navisworks on infrastructure projects,
37:43
and you have enough knowledge to adapt the roadway
37:45
and bridge development workflows of other Civil 3D-related
37:48
projects.
37:49
Today, we covered the exporting of discipline-specific models
37:52
from Civil 3D, preparing a federated model
37:56
for review in Navisworks, performing the model review,
38:00
recording and sharing findings with the extended design team,
38:05
and using SwitchBack to find an object in Civil 3D
38:08
and then refresh the Navisworks model with the updated design
38:11
model.
38:12
As I mentioned at the start, these
38:13
are not all the features of Navisworks,
38:15
nor was this intended as a detailed training class.
38:18
So we shall now highlight some additional resources
38:20
that can support your learning.
38:22
Please refer to these links, courses, and coaching classes
38:25
that are available to you.
38:27
I'd particularly like to highlight
38:28
the Online Help, which is a complete reference
38:30
guide to Navisworks.
38:32
The AU Presentations have access to many infrastructure
38:35
and Navisworks-related class recordings
38:37
from many Autodesk Universities gone by.
38:40
The Navisworks Product Page has additional product information
38:43
and feature overview videos.
38:45
I'd like to point out the Navisworks Freedom Download
38:47
link.
38:47
Share this link with your extended design team
38:49
and clients so that they can freely
38:51
view your Navisworks model, as well as your comments
38:53
and mark-ups.
38:54
The Customer Success Hub has a number of courses,
38:57
such as Coordination and Collaboration, where you'll
38:59
learn better ways to collaborate and to be
39:01
more efficient with BIM.
39:03
The Conceptual Design for Civil Engineers,
39:05
learn how various tools can help you articulate your design
39:08
ideas faster, while saving time later by reducing rework.
39:12
And Coordination and Work Sharing
39:14

Hi.
00:11
My name is Simon Jones.
00:12
I'm an independent BIM consultant,
00:14
and today I'm going to give you an introduction on how
00:16
to use Navisworks on infrastructure projects.

00:33
My name is Simon Jones.
00:34
I worked for Autodesk for 35 years,
00:36
where I had a variety of roles for product support, product
00:39
development, technical sales, and consulting.
00:42
I left at the start of 2021, and I'm now an independent BIM
00:45
consultant.
00:47
I've been working with Navisworks since well
00:48
before it was acquired from Autodesk, when it
00:51
was an independent application.
00:52
I'm based near Guildford in the UK.
00:55
Autodesk Accelerators are designed
00:57
to help your team stay ahead of the curve with the latest
00:59
workflows.
01:00
They include courses, videos, and live coaching, which
01:03
is what we're doing today.
01:05
You can see a full list of topics on the Customer Success
01:08
Hub.
01:09
Navisworks can combine separate models
01:11
from different disciplines into a single lightweight,
01:13
multi-discipline model.
01:15
Navisworks can import models from many different products
01:18
and file formats.
01:19
These include all sketch products,
01:21
such as AutoCAD, Revit, Civil
01:25
as [INAUDIBLE] sketch products, such as MicroStation DGN, IFC,
01:29
and SketchUp files, to name a few.
01:31
The resultant model is lightweight and easy
01:33
to navigate around, making it ideal to share
01:36
with an extended design team and support a design review
01:39
meeting.
01:40
A typical workflow for working with Navisworks
01:43
on infrastructure projects has the following main steps.
01:46
First, we export the models from Civil 3D
01:49
as a Navisworks NWC file.
01:52
In this example, we shall be focusing on Civil 3D.
01:54
But in many infrastructure projects,
01:56
there are likely to be a mix of other products,
01:58
such as Revit for building models, on the site.
02:01
And the same principles broadly apply.
02:04
Separate discipline-specific models
02:06
can be combined together in Navisworks
02:08
as a single coordinated multi-discipline model.
02:11
This model can then be used to perform a virtual review
02:13
to demonstrate intent, present progress, and capture
02:16
design issues.
02:17
Issues can be exported as reports to the design team
02:20
to be addressed, and updated models
02:22
can refresh the Navisworks models to tracking resolutions.
02:25
Finally, the model can be published and archived
02:27
as an accurate record of the design
02:29
at any stage of the project.
02:32
This Accelerator provides a quick overview
02:34
of using Navisworks on infrastructure projects.
02:36
The workflow will be based on a roadway and bridge development
02:39
designed in Civil 3D.
02:41
The main topics and overall learning objectives
02:44
we will be covering today are as follows.
02:46
First, we shall learn how to export
02:48
discipline-specific models from Civil 3D.
02:51
Then we shall aggregate the discipline-specific models
02:53
into a single coordinated multi-discipline model
02:56
in Navisworks.
02:57
Before starting the review, we shall learn some Navisworks
02:59
good practices in setting up orientations using Search Sets,
03:03
in order to make the review process as efficient
03:06
and streamlined as possible.
03:07
Once the Navis model has been set up,
03:10
we learn how to navigate around it
03:11
from a virtual tour of the site.
03:14
We shall learn how to take measurements of the model
03:16
and capture those as redline mark-ups
03:18
in annotated viewpoints.
03:20
We shall also see how the model can be used for clash detection
03:23
in order to find interferences between the disciplines,
03:25
as well as how to create a construction sequence.
03:28
We shall learn how to export reports and publish the model
03:31
to report back issues to the design team.
03:34
And, finally, we shall use SwitchBack
03:36
to identify an object in the Civil 3D model
03:38
and demonstrate how to make a change
03:40
and then refresh the Navisworks model.
03:42
Not all the features of Navisworks,
03:44
nor is this a detailed class.
03:46
Instead, this Accelerator is intended
03:49
as an introduction to using Navisworks
03:51
on infrastructure projects.
03:53
Additional links will be provided
03:54
at the end of the webinar if you wish to investigate Navisworks
03:57
further.
03:58
This Accelerator consists of single delivery session
04:01
with an overall delivery time of around 45 to 60 minutes.
04:04
And all products in this presentation
04:06
are utilizing the 2022 versions.
04:10
Let's take a look at how we can export the NWC
04:12
files from Civil 3D.
04:15
When exporting a Navisworks file from AutoCAD,
04:17
the visible entities will be the ones exported.
04:20
So entities with frozen or off layers will not be exported.
04:24
In Civil 3D, they are objects you would not
04:26
want in an a Navisworks model.
04:27
So simply freeze their layers.
04:30
Then, before performing the export,
04:31
I would recommend that you save a 3D view with a name
04:34
such as Navisworks Export.
04:36
And ensure that the Save Layer Snapshot option is enabled,
04:40
so that you could restore to save status any time.
04:44
The NWOPT command in AutoCAD opens the Navisworks Options
04:47
Editor to DWG files.
04:49
Within this dialog, you can fine-tune
04:51
how AutoCAD objects converted.
04:53
In most cases, default settings will be fine.
04:56
But take time to familiarize yourself with these settings.
04:59
To export the model, enter the NWCOUT command
05:03
and select a folder to write the Navisworks NWC file to.
05:08
In order to avoid superfluous geometries,
05:10
we're going to set up a view in Civil 3D
05:12
that has just the relevant geometry.
05:14
In this example, to export just electrical pylons,
05:17
we shall first create an AutoCAD view
05:19
that saves current viewpoint as a layer snapshot.
05:22
So we're going to call this one All 3D,
05:24
and we're going to check Save Layer Snapshot With View.
05:28
And set it as current.
05:31
Next, we're going to use the layer freeze tool
05:34
and freeze the geometry we don't want to see.
05:36
So these surfaces, and these lines,
05:39
so that all we're left with is those electrical pylons.
05:48
Once we have the view and the objects we want,
05:51
we're going to save this as another view.
05:53
Go into the View Manager, and this time we're
05:57
going to call it Navisworks Export, or something like that.
06:02
As people know, this is the one we export our models from.
06:06
And, again, make sure Save Layer is on.
06:14
With two views now set up, you can always go back to a working
06:18
view-- there's our All 3D--
06:19
as we were at the beginning of the process.
06:24
Or we can quickly go back to the Navisworks Export, which
06:28
has the objects we have in the model that we want to export.
06:32
And once we're happy with that, we run the NWCOUT command,
06:36
specify name, and save it to our hard disk.
06:43
Notes.
06:43
You can open AutoCAD DWG files, as well as many other file
06:46
formats, directly in Navisworks, and it'll
06:49
be automatically converted into a Navisworks NWC file.
06:52
Whilst this can be part of a successful workflow,
06:55
there are two issues to consider.
06:57
Firstly, it is less obvious which
06:59
geometry will be included.
07:01
In the AutoCAD export option, what-you-see-is-what-you-get
07:04
approach is far more predictable.
07:06
Also, when importing DWG files from Civil 3D
07:10
as opposed to standard AutoCAD, the relevant Object Enablers
07:13
need to be installed on a machine
07:15
running Navisworks works in order
07:17
to read non-standard AutoCAD objects, such as TIN surfaces.
07:21
We shall now take a look at how to aggregate
07:23
the discipline-specific models into a single federated
07:26
multi-discipline Navisworks model.
07:29
Typically, the federated model is
07:31
created by a model coordinator, who could, for example, work
07:34
for a general contractor.
07:35
Their role will be to create a coordinated multi-discipline
07:38
model that can be reviewed by members of the extended design
07:41
team, subcontractors, or client representatives.
07:44
As previously mentioned, the design models
07:46
can be a combination of different file formats,
07:48
such as AutoCAD DWG, IFC, and Revit RVT.
07:53
Whenever are these files are read indirectly or exported
07:56
from design applications, Navisworks imports the data
07:59
as an NWC file, which stands for Navisworks Cache.
08:03
When the NWC files are read into Navisworks,
08:06
the file could be saved as an NWF file.
08:09
This stands for Navisworks File Set.
08:12
This is a live file that simply references
08:14
the discipline-specific geometry and metadata
08:17
from the design application saved in the NWC files.
08:21
If the underlying NWC files are updated,
08:23
the updates are reflected in the NWF file,
08:26
enabling an iterative review and update of the design.
08:29
The NWF also stores Navisworks-specific data,
08:33
such as annotated viewpoints and comments that will
08:36
be explained in this session.
08:37
At any point, the data can be encapsulated
08:39
into a single NWD file, which stands for Navisworks Document.
08:44
But perhaps Navisworks Distributable
08:46
would be a better name.
08:48
An NWD file is much like a ZIP file that
08:50
contains all the design geometry and the metadata,
08:53
as well as the Navisworks-specific
08:55
data, such as the annotated viewpoints and comments.
08:58
Whilst an NWD file has lost its ability
09:01
to update the changes to the NWC files,
09:04
it does mean it is ideal for archiving a state of the model
09:07
with all the associated design review
09:09
information for future reference.
09:10
Not only that, an NWD file can be viewed free by anyone
09:14
using the Navisworks Freedom viewer.
09:17
In order to create a federated Navisworks model,
09:20
we're going to start by opening one of the NWC files.
09:23
In this case, we're going to open the electrical file.
09:26
And we're not seeing any geometry,
09:27
so we're going to pick on the Viewpoint that
09:29
was imported to Navisworks Export
09:31
to align ourselves with the view we had inside AutoCAD.
09:35
Additional files can then be appended to this.
09:39
So we're going to start off with the water, storm water,
09:41
and sewage water piping systems.
09:44
Add those into our model, and see those in place now.
09:50
Next, we will append some more files.
09:54
In this case, we're going to go for the bridge--
09:58
there it appears in the middle--
09:60
and, finally, we'll add in the road itself.
10:04
Now, before we get lost let's zoom out
10:07
and save the current Viewpoint as a home view.
10:22
Do this from the Viewpoint ribbon.
10:23
Save Viewpoint, and we're going to call it Home.
10:28
This way, if we get disorientated,
10:30
we can always come back to a set place.
10:39
Next, we're going to replace the black background
10:41
with a graduated blue background.
10:51
And this would be a good time to save our progress.
10:54
This now is going to save as an NWF file.
10:59
I'm going to call it Infrastructure Intro.
11:01
So these NWC files you see in the selection tree are just
11:05
being referenced in.
11:06
And any changes to those files will update this model directly
11:09
when they're reloaded.
11:11
Key to running a successful model
11:12
review is to set up some viewpoints that
11:14
will enable you to quickly jump to areas of interest.
11:18
This is especially useful if you have a large audience
11:20
in the design review, to avoid time being wasted
11:22
during a meeting wandering aimlessly
11:24
around the virtual world.
11:27
Before setting up any viewpoints,
11:29
it's worth making some changes to some global settings.
11:32
If you open up the Options Editor
11:34
and navigate down to the Viewpoint Defaults,
11:38
you'll find three settings.
11:39
Save Hide And Required Attributes,
11:42
Override Appearance, and Override Linear Speed.
11:45
By default, these are all unchecked.
11:47
I would recommend that you check all three of these options.
11:51
It's a global setting, so once it's done once,
11:54
it'll be saved for future use.
11:56
Secondly, you scroll down a bit further in the Options Editor,
11:59
come to Model, and in Performance, you'll
12:01
see there's an option called Close NWC/NWD Files On Load.
12:05
Likewise, this is off by default.
12:07
I always switch this on.
12:09
And what this means is you're able to overwrite a loaded NWC
12:14
file.
12:15
So you don't have to unload it if you make changes to update
12:17
your model in a live session.
12:20
Once again, it's a global setting.
12:21
Only needs to be done once.
12:24
When displaying objects, the color
12:25
is determined by the design application.
12:28
In the case of Civil
12:30
be displayed based on its CAD color, which can result
12:32
in a confusing array of colors.
12:34
Good practice is to set up a color standard
12:37
so certain objects consistently display
12:39
in the same color across different projects,
12:41
so that they are easier to identify.
12:44
For example, you may want to display
12:45
precast concrete in light gray.
12:48
Structural steel could be in oxide red,
12:50
and mains water pipes could be light blue.
12:53
Navisworks includes a tool called the Appearance Profiler
12:56
that applies color overrides to objects based on properties
12:59
that identify them.
13:00
The configuration could be saved as a DAT file
13:02
for sharing between projects to support standardization.
13:06
Let's flip the model over and take a look at the below ground
13:09
surfaces.
13:11
Notice that two of the pipe systems
13:13
are blue, which is the color used in Civil 3D
13:15
AutoCAD to highlight objects.
13:18
So when we highlight an object, if it's blue, we don't see it.
13:22
We see the purple one.
13:23
We could see the blue one-- we can't.
13:25
So this is a good example of why we'd
13:27
want to override these colors.
13:28
We can't, also, tell the difference
13:30
between what pipes they are.
13:33
So we could take an individual pipe, like that one,
13:35
and override it and display it in yellow.
13:38
But this would be pretty tedious if we
13:40
were to go around the whole bottle recovering our pipes.
13:45
So what we're going to do is we've
13:46
created some search sets, which I'll explain in
13:48
more detail later, that highlights or finds
13:50
all the pipes on a certain system, in this case, sewage.
13:56
And for this, we're going to override its color
13:58
and make those yellow.
14:03
And we're going to repeat that process for water.
14:07
And this search finds all the water pipes and these ones
14:11
we're going to make light blue.
14:19
And for the storm water, we're going to make those orange.
14:26
Now we can easily identify our water, our sewage,
14:29
and our storm water pipes based on their color.
14:31
If you use the same colors consistently,
14:33
you always know which is which.
14:35
Now when I select that object, it is not blue anymore.
14:38
It's yellow, and it's easier to see.
14:43
Now, if we return to the normal colors,
14:45
we reset all appearances and we go back to the original colors,
14:48
blue and purple, we can show you another way
14:50
of doing this using the Appearance Profiler.
14:55
Here we're going to select the sets,
14:57
and we're going to apply the same colors in here.
15:02
So we're going to do it.
15:03
This could be good for many objects.
15:04
We're just doing these three sets of pipes.
15:06
So we're going to go to the sewage, the water,
15:08
and the storm water with the same colors.
15:13
Well, what we can do is we can save this as this DAT file
15:17
so that we can open it in another project and reuse it.
15:19
Simply hit Run, and the pipes on those systems
15:23
will get the color that's been assigned by the Appearance
15:26
Profiler.
15:30
Before we start a review, it's important to set up
15:33
some orientation viewpoints.
15:35
On large, complex sites, it's quite possible
15:38
to get lost in the 3D world.
15:39
For this reason, it's advisable to set up
15:41
these pre-defined viewpoints that you can instantly
15:44
relocate to.
15:46
First, review any views that aren't imported from the design
15:48
files, and consider moving relevant ones into an imported
15:51
folder and deleting any irrelevant ones.
15:54
Each view can save numerous properties and not
15:57
just a view direction.
15:58
They can also save the render style, which
15:60
sets whether the view is displaying materials or object
16:03
colors, the view projection that is
16:05
either prospective or orthographic,
16:07
the objects that are visible in the view and those that
16:09
are not, transparency state of objects,
16:12
the navigation mode, which sets whether you are pre-set set
16:15
to walk, fly, or orbit, as well as a default walking
16:18
or fly speed.
16:19
This is handy, as you would want to set a speed that is
16:22
appropriate for the location.
16:23
For example, within a room of a building,
16:26
the default of about four meters per second would be fine.
16:29
But flying across a large site, such as this one,
16:31
it would be too slow.
16:32
With this in mind, it's worth setting up
16:34
a series of views that will enable the model
16:36
coordinator or other team members
16:37
to efficiently review the design.
16:40
Here we have a number of views set up.
16:42
And in the Saved Viewpoints list,
16:43
we've created a couple of folders,
16:45
one for the imported views and one for some orientation views.
16:48
We started off with a bird's eye view,
16:50
flying in across the road at a default
16:53
speed of 4 meters per second.
16:55
As you can see, this would take forever to reach our bridge.
17:01
So I've set up a different view.
17:04
This one has got a fast speed at 100 meters per second,
17:06
which is far more appropriate if you're flying around like this.
17:10
You can crash.
17:12
I'm going to reorientate ourselves with an
17:14
Under the Bridge view.
17:18
And from this, we can walk around,
17:21
and I can use my mouse to look up and down.
17:25
And I can use the Realism modes to switch on Collision
17:28
and Gravity so that I can walk up the embankment
17:31
and I stay with my feet firmly on the ground.
17:34
If I use my mouse wheel, I can pan around,
17:36
and I can look up and down.
17:38
Now looking underneath the road, and we've
17:40
got Gravity switched off, because we wouldn't
17:42
want to fall down to eternity.
17:43
So we can wander around, walking around the piles,
17:47
checking the design without falling down.
17:56
Back on top of the road, I'm walking around.
17:58
But in this case, the road has had its transparency
18:03
set so that we can see the pipe runs underneath the road
18:07
surface as we're walking around.
18:09
So we can check the pipe design through the road.
18:12
So in some review ports, a powerful way
18:15
of setting up the model for an efficient review in a far
18:17
more than simply Save View directions
18:20
There are two main render styles that control
18:22
how Navisworks display objects.
18:25
The Shaded option displays objects using their color
18:27
and transparency setting, whereas the Full Render option
18:30
displays objects using materials, such as concrete,
18:33
brick, or grass, which will override the color
18:36
and transparency settings.
18:38
Should you wish to generate renders with even more realism,
18:41
Navisworks include a Ray Trace render
18:43
that will provide enhanced lighting and material control.
18:46
Whilst this is not as fast as a standard renderer,
18:49
there is an option to have the renders generated
18:51
in the cloud, which is significantly faster
18:54
and doesn't tie up a desktop machine.
18:56
The View Section feature enables you to slice through the model
18:59
in order to cut away nonrelevant geometry
19:02
or view hidden features, such as cross section
19:04
the structural composition of the bridge.
19:06
You can define single cut plains or, in the case of the example
19:10
on the slide, a box section that can isolate
19:12
an area of the model defined by a rectangular box
19:14
with four sides, a top, and a bottom.
19:18
To make a sectional view, we start
19:20
with entering the Enabling Sections
19:22
and picking the section mode we want to use.
19:24
We're going to use a Box.
19:27
And here we're using the Scale gizmo to move it around.
19:31
And here we can look up from above.
19:33
And we're going to use the Rotate option to rotate it
19:36
and line it up with our bridge.
19:37
Then we're going to move it in position,
19:41
and orbit back again, and scale it one more time.
19:49
So we cut away the area around the bridge,
19:51
and now we've got a nice, neat bridge we can look at.
19:54
We can pick on one of the items, or use
19:57
the Swivel to spin around our bridge without having
20:01
all the rest of the road to worry about,
20:03
and just cut away the area of interest,
20:05
which is just this bridge area, using that Section box.
20:08
This can be saved as a Viewpoint, which
20:10
we'll call Bridge Section.
20:11
And any time, we can jump between this
20:15
or any other Viewpoint, and the current section
20:17
will be remembered with that Viewpoint.
20:20
Selection and Search Sets are a powerful feature
20:23
for grouping together objects and they're
20:25
used as an essential skill for working
20:26
efficiently with Navisworks.
20:29
Use Selection Sets and Search Sets to group together items
20:32
for re-selection.
20:33
Selection Sets are named static groups
20:36
of items based on a manual selection,
20:38
whereas Search Sets are named dynamic groups of items
20:41
based on search criteria, which update automatically
20:44
as the model changes.
20:46
You can export Search Sets to XML files
20:49
for re-use across projects.
20:51
In this example, we shall use the Box selection
20:53
mode to create a Selection Set of just the roundabout objects.
20:58
We'll save this selection and call it Roundabout.
21:01
And then we're going to use Hide Unselected
21:03
so nothing else is visible other than the roundabout.
21:05
There you see we can select it again,
21:11
or we can come and select our Piles.
21:14
Here, we see our Piles are on a layer called Foundations.
21:18
So we're going to now create a Search Set called Foundations,
21:22
which is going to find all items which have a layer called
21:24
Foundations.
21:26
Or we can change the search criteria to Piers
21:31
and run the Find All, and we will
21:32
find all of the items that are on the Piers layer.
21:38
And we're going to call that Piers.
21:39
So now we've got two Search Sets, one called Foundations
21:42
and one called Piers.
21:43
We're going to place those in a folder called Structure.
21:47
And we can group them together.
21:48
We can drag these Search Sets into the folder.
21:57
And as we pick on those, you highlight the objects,
21:59
or we pick on the folder and it highlights all the objects
22:01
within those.
22:03
And we can even use Invert Selection to select
22:05
everything but our items.
22:08
In this case, we're going to make
22:09
everything else transparent, so if we
22:12
want to see our structure underneath our bridge
22:15
in context.
22:21
Once the Navisworks model has been prepared with Viewpoints
22:23
and Search Sets, it is ready to support the model review
22:26
process.
22:28
A necessary part of the model review
22:29
is to move around the model, and Navisworks provides three
22:32
different navigation options.
22:34
Which you use will be down to personal preference
22:37
and some subtle differences.
22:38
Originally, Navisworks included just the Navigation Bar,
22:42
with options such as Zoom, Pan, Orbit, Fly, and Walk.
22:46
However, once the product was acquired by Autodesk,
22:49
the Steering Wheel and ViewCube were also
22:51
included to provide a consistent 3D navigation
22:54
experience across the suite of Autodesk products.
22:57
Familiarize yourself with all three options,
22:60
as they all have their advantages.
23:02
The Measure tools can be used for measuring distances, areas,
23:06
and angles of the model geometry.
23:08
A neat feature is the option to measure the shortest
23:10
distance between two objects.
23:12
And if, for example, you just need the vertical distance,
23:15
you can enable the Lock feature to constrain the measurement
23:18
to just the z-axis.
23:20
Initially, measurements are displayed temporarily
23:23
on the view, but they can be converted into redlines
23:26
and saved to a viewpoint.
23:29
The Navisworks redlining tools are fairly basic.
23:31
But that does make them very easy to use,
23:34
and it will not take long to get familiar
23:35
with the tools, such as Cloud Ellipse, Arrow, and Text.
23:39
Once the redline is placed, it is automatically
23:42
added to the current view, or a new view
23:44
is created, if required.
23:46
Redlines disappear when you navigate away
23:48
from the viewpoint, but reappear when
23:50
the viewpoint is returned to.
23:52
In this demonstration, which starts with a Home view
23:55
and which we use with ViewCube to adjust the view direction,
23:58
the advantage being that we get a nominal compass
24:01
so we know which way we're pointing.
24:02
And we can use this to drag around.
24:08
Or I can switch to the Steering Wheel.
24:11
And I could go into a Walk mode, and I
24:14
can use this Steering Wheel to change it into an up-down mode
24:17
so it's all interactive on the screen.
24:20
Or I can use the back into Walk mode again, look down a bit,
24:27
move myself down, go back into Walk, all in one control.
24:37
Now I'm at my guardrail.
24:38
I actually want to see the height of this guardrail.
24:41
So I'm going to go to the Measure tools,
24:43
select the Point to Point option,
24:46
and I'm going to have the z-axis locked.
24:49
And I'm going to snap to the edges,
24:53
and I'm going to measure the vertical distance
24:55
between the bottom of the rails and the top.
24:57
As you can see, it's 0.8 of a meter.
24:60
And then I'm going to convert this to a redline.
25:02
And when I do this, it automatically
25:04
creates a new view, just called View,
25:06
which I'm now going to rename to Guardrail Height.
25:11
And I'm going to start a new folder called
25:15
Project Review, or Model Review, and today's date.
25:19
And I'm going to place my Guardrail Height
25:22
annotation into that folder.
25:25
Let's go off and have a look under the bridge.
25:30
I can look up and down with my mouse wheel.
25:33
And in this case, I want to measure
25:34
the distance between the road and the bottom of the bridge
25:37
to work out the clearance.
25:38
So I'm going to pick the two items.
25:40
With two items picked, I can use the Shortest Distance tool.
25:44
And it tells me there's 7.2 meters
25:46
from the road to the bottom of the bridge,
25:48
which, again, I convert to a redline.
25:50
That creates a view, which I'm going
25:52
to rename Bridge Clearance, and drag that view into my folder
25:57
for my Model Review.
26:02
Let's get back into Walk mode, and we're
26:06
going to wander around our road.
26:08
We're going to look for more things to inspect.
26:12
And first thing I notice, this lamppost
26:15
seems to be flying up in the air.
26:18
So we're going to get ourselves a good view of it.
26:25
And if I select it and look at its properties,
26:27
we can see that it's point number five.
26:29
That could be useful.
26:30
So I'm going to copy this information into the Clipboard,
26:33
that it's lamppost number five.
26:37
I'm going to go to the Cloud tool,
26:39
and I'm just going to quickly put a cloud around the area
26:42
and put an arrow in indicating that this lamppost really
26:47
should be down there somewhere.
26:49
And I'm going to add a little bit of text,
26:51
as well, to highlight the floating lamppost.
26:56
This, too, has created a view, which I'm going to rename to--
27:00
well, I'm going to add a Comment, first of all.
27:03
The comment is going to be that we've got a floating lamppost,
27:07
and I'm going to add the information on the point
27:09
number, since it could be useful to someone.
27:15
And this view we're going to rename Floating Lamppost,
27:18
and drag that into our Model Review.
27:20
You could have lots and lots of views in here
27:22
after a review meeting.
27:23
But I can now quickly jump between all of these views
27:26
and get a quick summary of all the issues I found
27:28
during our project review.
27:32
The Clash Detection feature in Navisworks Manage
27:34
will then analyze the model and report on interferences
27:37
between objects so that the design can
27:39
be rectified and avoid costly on-site resolutions.
27:43
Key to effective Clash Detection is not
27:45
to try and clash everything against everything,
27:47
but to focus on what items have the highest priority,
27:50
in terms of impact and time constraints.
27:53
An example of high-priority clash
27:55
is one involving foundations and underground drainage systems.
27:58
These items have high time-based priority,
28:01
since they're the earliest part of the construction.
28:03
And foundations have high priority relating
28:05
to clash resolution, in that moving foundations would have
28:08
a serious impact on the integrity of the structure,
28:11
and there would be significant repercussions
28:14
if they were moved or changed.
28:15
Furthermore, drainage systems that run on a fall cannot
28:18
simply be rerouted over or around an obstacle,
28:21
such as foundations.
28:23
Individual clashes can be assigned
28:25
to whoever needs to provide the resolution,
28:27
along with a status for tracking the progress.
28:30
And there's even a possibility to simulate clashes
28:32
with moving objects over a period of time, such as cranes
28:36
and other plant equipment.
28:38
In this example, we shall set up a clash test
28:40
to check the interference between bridge
28:42
foundations and the underground pipe systems.
28:48
So we've got the Search Sets set up to identify these objects.
28:51
And we'll open up the Clash Detection panel.
28:56
And we're going to add a test, where for the test name,
29:02
we're going to say it's Foundations versus Pipes.
29:05
And in the Selections, we're going to select our Sets.
29:09
So we're going to set the Foundations on one side,
29:11
and we're going to compare this with the Below Ground Services.
29:15
And we're going to pick the folder, which
29:17
is going to be for all services, Sewage Water, Water,
29:21
and Storm Water.
29:22
And we're going to run a test.
29:24
From that test, we can see we found
29:26
a single clash of a pipe running through our piles
29:29
underneath our bridge.
29:31
Notice how the piles are in red, pipes are in green,
29:34
and the rest of the model has been grayed out
29:37
so we can see it.
29:39
Now we're going to assign this to the drainage engineer
29:42
and ask him to reroute the pipe around the foundations.
29:48
We can set up a number of tests.
29:51
So we're going to add another test.
29:53
This time, we're going to actually check and make
29:54
sure our pipes are not intersecting with other pipes.
29:56
So we could do Pipes versus Pipes.
30:02
So for this, we're going to say all the Below Ground
30:04
Services against all the Below Ground Services.
30:08
And we're going to run the test.
30:11
This, however, has reported 79 clashes,
30:15
which is a lot to deal with.
30:20
If we look at these, we'll find, actually, a lot
30:22
of these clashes are where the pipes are actually
30:25
connecting into their concrete inspection chambers,
30:28
and things like that.
30:29
So they're not actually clashes, so we can ignore those.
30:32
So we're going to set up a couple of rules.
30:34
The one we're going to do is say it's not a clash
30:36
if it appears in the same file.
30:38
The little yellow triangle tells us this clash test is invalid.
30:44
So we'll now reset it, remove all the clashes,
30:47
and we're going to rerun that test.
30:52
This time, we only end up with one clash.
30:55
Here, we see we have a water pipe running through a sewage
30:58
manhole, which sounds a fairly high-priority one to fix.
31:02
So we're going to assign this one to the water engineer.
31:08
And we'll ask him to reroute his pipe around a manhole.
31:15
Once we've done the clash tests, we
31:17
have a number of ways of reporting the results.
31:23
First up, we're going to use the HTML Tabular report.
31:27
We're going to write a report, and it
31:29
writes as an HTML file, which can be seen as such.
31:33
So you see those two clashes we found
31:35
and all the information about them
31:36
and who they're assigned to.
31:38
The HTML file can also be read in Excel.
31:42
And here we see it as an Excel file,
31:43
which, again, can be just emailed off to the design team
31:46
to fix.
31:48
Alternatively, we could save the report as viewpoints.
31:53
So when we write this report, we end up
31:56
in the Save Viewpoints list as some viewpoints
31:59
of each of the clashes.
31:60
So there's clash one, of the foundations with the pipe,
32:03
and here's the clash of the pipe going
32:04
through the manhole cover.
32:07
So we can inspect them in context
32:09
of the rest of the model.
32:11
The Navisworks TimeLiner feature can
32:13
be used to create
32:15
such as construction sequences, that
32:18
can animate a virtual construction based on a project
32:21
schedule.
32:22
Items in the model can be linked to a task schedule linked
32:25
to a project plan, which can be developed within Navisworks
32:28
or imported from planning applications,
32:31
such as Microsoft Projects or Primavera P6.
32:35
The task hierarchy is displayed clearly as a Gantt shot
32:38
within the TimeLiner panel.
32:40
The simulation can represent items being constructed,
32:43
demolished, or temporary works.
32:45
It is even possible to have items
32:47
moved during the simulation to represent plant movements,
32:50
such as cranes turning.
32:52
Once generated, the simulation can
32:54
be exported and shared as a video file
32:56
or replayed within Navisworks.
32:59
Here we see the bridge with the TimeLiner module.
33:02
Included with the model is a pile driver
33:04
that we should include in our construction simulation.
33:09
The task list has a hierarchy that
33:11
has main tasks and subtasks.
33:14
We can develop this list directly inside the Navisworks
33:17
panel we've got here.
33:22
Or we can switch to the Data Sources tab
33:24
and import these from products like Microsoft
33:27
Projects and Primavera P6.
33:31
Each of these tasks can be assigned start and end dates.
33:37
We can assign task types, such as whether they're
33:41
construction, demolition, or temporary tasks.
33:45
We can assign the objects associated with those tasks.
33:51
And we can even assign whether or not
33:53
there's an animation associated.
33:55
So each of the pile driver tasks we've
33:58
assigned an animation that will drive the pile
34:01
driver across the piles.
34:08
To run the simulation, we switch to the Simulation tab and hit
34:12
Play.
34:13
And the simulation will play out across the screen.
34:16
And in the viewpoint, we'll see the state of the model
34:19
on any particular day.
34:20
At any point, we can stop it, inspect the project progress
34:24
for any given day, and then continue until the construction
34:27
sequence is complete.
34:28
And here we see the final completed construction sequence
34:32
after day 42, or week six, of our simulated construction.
34:37
Once the model has been completed,
34:38
it is necessary to report the findings
34:40
with whoever needs to know.
34:41
This is most likely to be project managers, discipline
34:44
leads, and a design team, but may also
34:46
include the client, who simply wants
34:48
to have an overview of the project progress.
34:51
Annotated views can be exported as a simple image,
34:54
or all the mark-ups and comments attached to viewpoints
34:56
can be written to a Viewpoint Report
34:59
in HTML format, which includes viewpoint thumbnails.
35:02
Earlier, we already saw how Navisworks
35:05
generates clash reports and explained
35:07
how 4D construction sequences could
35:09
be exported as video files.
35:11
However, the most powerful option
35:12
is to publish the review to an NWD file that encapsulates
35:16
all the information, including the actual state of the review
35:19
design and all viewpoints, comments, and mark-ups.
35:23
An NWD is a single file much like a ZIP file
35:26
that includes all the model geometry and the Navisworks
35:29
information as a snapshot.
35:31
In this case, updates to the original NWC cache files
35:35
will not update the NWD file, making
35:38
it ideal for accurate record of the model for a given date.
35:42
Furthermore, the NWD file can be viewed, but not edited,
35:46
by anyone using the free viewer, called Navisworks Freedom,
35:49
enabling anyone access to the information.
35:52
However, in the case of sensitive information,
35:55
an NWD file can also be password protected
35:58
to protect its confidentiality, or given an expiry date so
36:01
that it is not inadvertently referenced
36:04
after it is considered to be out of date information.
36:07
SwitchBack enables you to select an object in Navisworks
36:10
and then locate and zoom into the same object
36:13
in the originating design applications, such as Civil 3D
36:16
in this example.
36:18
The native CAD package must be installed
36:20
and running on the same machine as Navisworks for SwitchBack
36:23
to work.
36:24
And, in the case of AutoCAD, it is
36:26
necessary to first run the NWLOAD command
36:28
to load the NW Export plug-in so that it
36:31
is primed for the SwitchBack.
36:33
To perform a SwitchBack, locate an item in Navisworks
36:36
and select the SwitchBack option from the Item menu.
36:40
AutoCAD will then attempt to locate the equivalent AutoCAD
36:42
entity in Civil
36:45
Back in the floating lamppost view, we select the lamppost
36:49
and then select SwitchBack from the menu.
36:51
Over in Civil 3D that is running on the same machine,
36:54
the equivalent lamppost has been identified and selected.
36:57
In this example, we shall simply use the Move gizmo
36:60
to drag the lamppost down to approximately
37:02
the right elevation.
37:04
We shall then re-export the model using the NWCOUT command
37:08
to write a new NWC file and override the existing one.
37:15
Back in Navisworks, we can simply
37:16
select the Refresh tool to reload the updated NWC file
37:20
and the lamppost will drop down to the right position.
37:24
Now that we are happy the issue has been fixed,
37:26
we shall edit the Comment on the viewpoint
37:28
and change its status to resolved.
37:38
Hopefully this session has provided a good overview
37:40
of using Navisworks on infrastructure projects,
37:43
and you have enough knowledge to adapt the roadway
37:45
and bridge development workflows of other Civil 3D-related
37:48
projects.
37:49
Today, we covered the exporting of discipline-specific models
37:52
from Civil 3D, preparing a federated model
37:56
for review in Navisworks, performing the model review,
38:00
recording and sharing findings with the extended design team,
38:05
and using SwitchBack to find an object in Civil 3D
38:08
and then refresh the Navisworks model with the updated design
38:11
model.
38:12
As I mentioned at the start, these
38:13
are not all the features of Navisworks,
38:15
nor was this intended as a detailed training class.
38:18
So we shall now highlight some additional resources
38:20
that can support your learning.
38:22
Please refer to these links, courses, and coaching classes
38:25
that are available to you.
38:27
I'd particularly like to highlight
38:28
the Online Help, which is a complete reference
38:30
guide to Navisworks.
38:32
The AU Presentations have access to many infrastructure
38:35
and Navisworks-related class recordings
38:37
from many Autodesk Universities gone by.
38:40
The Navisworks Product Page has additional product information
38:43
and feature overview videos.
38:45
I'd like to point out the Navisworks Freedom Download
