How Linking to AutoCAD Files Works

When you link an AutoCAD file to a project, Revit Architecture maintains a link to that file. Whenever you
open the Revit project, Revit Architecture retrieves the current, saved version of the linked file and displays
it in the project. Any changes to the linked file are displayed in the Revit project. If the linked file changes
while the Revit project is open, reload the file to retrieve the latest changes. (See
1222.)
This ability to retrieve the latest changes to an AutoCAD file is the difference between linking and importing.
When you import an AutoCAD file, Revit Architecture uses the version of the file that you imported. It does
not retrieve or display changes to the imported file.
When you link (or import) an AutoCAD file to a Revit project, you can do the following:
Query objects in the file
Hide or delete selected layers in the file
Change the graphic display of layers in the file
When you link a file to a Revit project, you can control whether the linked file is visible only in the current
view, or in all views. As a 2D drawing, the linked file is displayed only in relevant 2D Revit drawings, such
as floor plans. In a 3D view, the linked file is displayed as flat, 2D shapes.

Linking to an AutoCAD File

1 Open the Revit project.
2 If you want the linked file to display only in a particular view, open that view.
3 Click File menu
4 Specify the file to link, as follows:
For Look in, navigate to the location of the file.
For Files of type, specify DWG.
For File name, specify the name of the file.
5 To link the file (instead of import it), do the following:
a If you want the linked file to display in the current view only, select Current view only.
If you do not select this option, the linked file is displayed in all relevant 2D views, such
as floor plans.
b Select Link.
c For Layers, select one of the following values:
All: Displays all linked file layers in the Revit project, including hidden layers.
Visible: Displays visible layers of the linked file in the Revit project. Layers that are
currently hidden in AutoCAD do not display in Revit Architecture.
Specify: Allows you to select the layers to display in the Revit project from a list. After
you click Open, Revit Architecture displays the list of layers from which to choose.
6 Specify the desired import options.
