Tip Title:      Prevent Imported CAD Styles

Product:      Revit

Author:        Glenn Sinclair – Technical Consulting Lead



When importing or linking CAD files, many junk styles are imported into the Revit file.



To prevent these junk styles such as line patterns from being imported, the CAD files must be linked into an intermediate “clean-up” Revit file, before being linked into the main documentation Revit file(s).


Example of imported styles in Manage>Additional Settings>Line Patterns



When working with consultants CAD files, these would be imported into the clean-up “CADLinks.rvt” in current view only (in 2D).


A separate view should be created for each CAD background, Levels are not needed when importing in 2D, the Default “Ground Floor” view can be duplicated to host these files.

The two types of views are generally Documentation views and Coordination views. Documentaiton views are when information from the consultants CAD file is to be printed on your drawing, Coordiantion is when we will be turning the information on temporarily for coordination purposes. These can be split using browser organisation for clarity.

Documentation views may contain more than one CAD file linked in, with the layers hidden etc. to suit the final printed document, the naming may be “Doc Background Level 01”, “Doc Background Site”.

Coordination views generally contain one consultants file, possibly with some layers turned off for clarity, the naming may be “Coord Structural Level 02”, “Coord Mechanical Level 01”.


Once the views are setup, the “CADLinks.rvt” file should be Linked into your main Revit model(s) using “Link Revit”. Ideally Shared coordinates should be setup and used here.


The CAD background can now be set in the Visibility Graphics for each view (or using a view template). On the Revit Links tab, click the Display Settings button, change to “by Linked View” then select the appropriate view from the drop down box.
