00:03
In a Revit model, linked CAD files can be used as an underlay to trace building objects
00:09
such as walls, doors, and windows.
00:12
When linking AutoCAD data in your project, it is important to ensure that the CAD file is pinned, so that it maintains its position.
00:20
To begin, open a project with a linked CAD file.
00:24
In this example, a CAD file with walls is used.
00:28
To distinguish the CAD lines more easily, zoom in on a building object, such as a corridor wall.
00:34
Then, on the Quick Access Toolbar, enable Thin Lines.
00:38
This displays all lines in the project as a single width.
00:43
If you want to match the thickness of the walls in the CAD file,
00:46
you can measure them to determine their thickness.
00:48
On the Quick Access toolbar, click Measure Between Two References.
00:54
Hover the cursor over the walls and the CAD lines highlight.
00:59
Click on the face of a wall, then click on the other face of the same wall.
01:03
When you do, a temporary dimension displays.
01:07
Now, place walls over the CAD file underlay.
01:11
From the Architecture ribbon in the Build panel, click Wall.
01:15
Next, expand the Type Selector drop-down and choose a wall with matching dimensions as the temporary dimension.
01:23
Then, in the Properties palette, set Top Constraint to Level 1.
01:28
Set the Location Line to Finish Face: Exterior.
01:32
With the wall type configured, you can trace the walls.
01:35
From the ribbon, Draw panel, choose Pick Lines.
01:40
Begin placing the corridor walls based on the interior walls of the CAD file.
01:45
When you hover the cursor over the finish face of a wall, a dotted line appears.
01:50
The line is positioned based on the location line.
01:54
In this instance, with Finish Face: Exterior selected, the dotted line indicates the wall centerline
02:00
based on the wall type you specified.
02:02
Once the dotted line is positioned correctly, click to place the wall.
02:07
If you place a wall in the wrong location, you can use the flip control to correct its placement.
02:14
You can place one wall on each side of the corridor and use the Trim/Extend to Corner tool to help connect walls.
02:22
With this tool activated, simply select the two walls you want to extend to form a corner.
02:29
When you are finished, click Modify to end the command.
02:33
Using a linked CAD file is an easy way to recreate building objects in Revit.
