SPEAKER: When you're starting off a factory brownfield
00:09
project, it's incredibly important
00:11
that you verify the existing conditions of the facility
00:14
that you're going to be working with.
00:15
In this lesson, we want to make sure
00:18
that your initial setup is as accurate and consistent
00:21
as possible.
00:27
The overall objectives for this course
00:29
are to learn how to utilize the various types of documents
00:32
you'll find when you're verifying the existing
00:34
conditions of a brownfield facility.
00:38
We also want to explore the use of Laser Scan Point Clouds
00:41
to capture the existing conditions of the facility.
00:45
And we'll finish up showing you how to utilize a Point
00:47
Cloud in a factory layout.
00:50
I think the first thing we need to do
00:52
is define what a brownfield project is.
00:55
In the scenario we're going to cover today,
00:58
a brownfield project is simply an existing building
01:01
we will be developing to support a new factory layout.
01:04
Instead of building a new building, which
01:07
would be a greenfield project, we're
01:09
going to be utilizing and upgrading
01:10
an existing space or building.
01:14
Let's focus on the initial process for developing
01:16
a brownfield project.
01:18
The entire factory design utility process
01:20
begins by establishing the footprint of the existing space
01:24
or building.
01:25
Usually, this consists of generating a simple 2D AutoCAD
01:28
footprint and, optionally, a 3D model of the building.
01:33
The first rule of the factory utility layout process
01:35
is quite simple, and extremely important.
01:38
All layout design work must be placed in context
01:41
of a common origin point.
01:43
The origin point is often determined
01:45
by the original architectural footprint, created in AutoCAD,
01:49
or AutoCAD Architecture.
01:51
Any time an asset is placed in a layout,
01:53
it must be placed in proper spatial relation
01:56
to the overall design origin, or 0,0 point.
01:60
This allows the overall layout design
02:01
to be divided into multiple supporting sub layouts,
02:05
and ensures that all layout work aligns properly
02:07
when assembled into the final Navisworks digital mockup.
02:12
When developing the initial
02:15
it is extremely important to verify the existing conditions
02:18
and record them accurately.
02:20
This process usually takes place in the AutoCAD application.
02:24
There are several legacy document types
02:26
that you may choose to take advantage of.
02:29
The conditions of an existing building
02:31
have probably been documented several times
02:32
throughout its history.
02:34
It is common to start a brownfield project
02:36
with an old hand drawing, a PDF record, or even
02:40
legacy AutoCAD drawings.
02:42
Each of these formats presents possible pitfalls or obstacles
02:46
that must be considered before committing the information
02:49
to a new production design.
02:52
Hand drawings or sketches that contain manual tape
02:55
measurements need to be verified before use.
02:58
This old method of documentation is error-prone and unreliable.
03:02
Often a missing dimension or detail
03:03
will derail the entire project until the critical information
03:07
is discovered.
03:08
If you are dealing with hand drawings, at some point
03:11
you know you'll have to redraw the building
03:12
footprint in AutoCAD.
03:15
AutoCAD Architecture is usually the best choice
03:17
for this process.
03:19
AutoCAD Architecture has specific commands
03:21
to generate walls, windows, doors, columns,
03:26
and column grids.
03:28
This is usually all that is required
03:30
to define the layout space.
03:32
It's important to set the common origin
03:34
point of the overall project in your drawing.
03:38
Now there's no way I can teach you
03:40
how to use AutoCAD Architecture in just a few minutes,
03:43
but I can give you a few good hints to get started.
03:46
When you open up AutoCAD Architecture,
03:48
I think the first place you want to go
03:50
is right here on the Home tab, the Tools area.
03:54
This allows you to bring up your design tools.
03:57
And I'd also encourage you to bring up
03:58
your properties palette.
04:01
You're going to use the commands on these two pallets
04:04
to generate most of the architectural work
04:06
that you're going to need to produce.
04:08
Let me show you how easy it is to create
04:10
a wall in AutoCAD Architecture.
04:13
I like to say that, if you can draw a line,
04:15
you can create walls in AutoCAD Architecture.
04:19
So, for instance, if I want a 10 foot wall.
04:27
Here you can see I just made a simple square room.
04:30
Well, let's go ahead and add a door,
04:31
so that we can get into this room.
04:33
I'm simply going to start the door command
04:40
and select and place the door.
04:47
The same thing with the window command.
04:49
I can start that command and place a window
04:52
wherever I want it.
04:55
You can utilize the options in the Properties palette
04:59
to adjust the sizes of the doors and windows to suit.
05:07
I think one of the most amazing things that I've discovered
05:09
about AutoCAD Architecture, is that what
05:12
I perceive to be just simple 2D line work is actually 3D data.
05:18
Let me show you what I mean.
05:19
I'm going to go to my Home view.
05:21
And you'll see that all of my seemingly 2D line work
05:26
is actually 3D data.
05:29
And if I were to change my visual style to something
05:33
like realistic, you'd actually see
05:36
it rendered very, very well.
05:38
So if you find yourself having to produce 2D footprint
05:42
drawings, I really would encourage
05:44
you to utilize AutoCAD Architecture to do so.
05:47
It is also common to discover PDF files of the original CAD
05:51
drawings.
05:52
It is important to remember that PDF files generated directly
05:55
from a CAD system may be converted back to vector lines.
05:60
AutoCAD has the Import PDF command that accomplishes this
06:04
very easily.
06:06
You need to remember that drawing precision may
06:08
be affected by this process and needs to be checked.
06:12
Make sure to double check any critical dimensions.
06:15
You also need to make sure to set
06:17
the origin to the common point of the project.
06:22
In many cases, you'll find legacy AutoCAD drawings
06:25
for the brownfield building or space.
06:28
It is important to remember that older drawings may not
06:30
reflect the current state of the facility.
06:33
Manual verification of critical dimensions are still necessary.
06:38
As with all these document types,
06:40
it is important to move the drawing
06:42
origin to the appropriate location in way
06:44
of the new project.
06:47
The footprint of the building or space
06:49
will typically be used as the basis for the new layout
06:52
design.
06:53
Often, the first step in the factory utility process
06:56
is to add the DWG underlay to the factory floor in Inventor.
07:01
Notice that the building footprint
07:02
is placed at the common origin point, as
07:05
defined in the original AutoCAD drawing.
