the Analytical Model in Revit, Applying Support Conditions.
00:06
In this video, we'll step through the process
00:08
of disabling the analytical model
00:10
for several structural foundation elements
00:13
and defining the boundary conditions for the elements
00:16
in the analytical model.
00:18
I'm working in the small medical center project.
00:21
It opens in a 3D analytical model view.
00:24
This is a simplified representation
00:26
of the full engineering description
00:28
of the structural physical model,
00:30
including the structural components, geometry,
00:33
material properties, and loads.
00:36
The analytical model is created by default
00:38
as you create the physical model.
00:41
I'm now going to open a 3D view that shows the physical model.
00:47
Now I want to see both views, so I'm going to type WT
00:52
to tile the views.
00:54
And then I'm typing ZA to zoom them out.
00:58
I want to make sure that I'm seeing them
00:60
both in the same direction.
01:02
So, I'm going to right-click on the View Cube,
01:04
orient to a direction, and select Northeast Isometric.
01:09
And then I'm going to do the same in this view--
01:12
Orient to a Direction, Northeast Isometric.
01:17
Now that I'm in the same direction,
01:20
I want to show that I have my analytical columns
01:22
here and my columns in the main building.
01:26
I'm going to select several foundation elements as well
01:32
as this wall back here.
01:37
And what I want to do now is I want to disable
01:40
the analytical model.
01:41
I'm going to separate it from the physical model.
01:44
So in Properties, I click Enable Analytical Model,
01:48
and it clears the check.
01:50
In this case, we want to specify the boundary conditions
01:53
separately from the model to give better control
01:56
and bidirectional compatibility when
01:58
the model is exported to Robot for structural analysis.
02:03
Now I'm going to click in the Analytical Model View.
02:05
You can see there's no difference in visibility
02:08
whether it's set to analytical or not.
02:12
Now I'm going to zoom in on the model,
02:14
and I'm going to go into the Analyze tab, Analytical Model,
02:18
and select Boundary Conditions.
02:21
Then I want to choose a point boundary condition.
02:24
And I want to set it to fixed, and I'm
02:27
doing that in the Options bar.
02:30
I click on the bottom of each of these columns in this area,
02:34
and I'm specifying the boundary condition.
02:38
I'm still in the command.
02:40
I'm going to go up and change it to the line
02:42
type of boundary condition.
02:46
And then I'm going to change the state to pend.
02:50
And now, when I pick this foundation wall,
02:53
you can see that I have a different style of icon.
02:57
So I picked modify, and now I'm just looking.
02:59
Here's my boundary condition.
03:02
This one here, which was already in place,
03:04
as you can see in properties, was an area boundary condition
03:08
because it was connected to a structural floor You want
03:12
to add boundary conditions to a model
03:14
so you can better control the bidirectional compatibility
03:17
when the model is exported to Robot for structural analysis.

03-001 Practice - Developing the Analytical Model in Revit : Applying Support Conditions
In this practice you will step through the process of enabling/disabling analytical model for structural foundation elements and defining boundary conditions for analytical model.
12. In the Ribbon, change the Boundary to Line. In the Options Bar or Properties set the state to Pinned and select the wall.
13. Click Modify to end the command. You can see the difference between the two icons for Fixed and Pinnned conditions.
14. Select the nearby boundary condition, as shown below. Notice that is an Area boundary and its state is set to Pinned it is connected to the structural floor.
15. Add boundary conditions to the model so you can better control the bidirectional compatibility when the model is exported to Robot for structural analysis.
