Interfence Detection

A benefit of using Revit is the ability to do an interference check with other disciplines.


To run an interference check, first attach any discipline,like structural, that might not be in the central model. In the 2009 version of Revit go to the File menu and select Import/Link then Revit.

In Revit 2010, go to the Insert tab and select Link Revit. Make sure to link using Origin to Origin.

Select Interference Check then Run Check from the Tools menu in 2009 and off the Collaborate tab in 2010.

Revit let's you pick what to check. The example below shows light fixtures in the current model checked against structural framing in the BK file.

Any interferences will be shown in the interference report. Select the interference in the report then select the Show button to see the interference in the model.
Once the interference has been addressed, click the Refresh button to clear it from the report.

Do not run an entire model against another entire model. Revit hates that. Run the check specifically on the items that are of concern, like duct and mechanical equipment against structural framing, or lights against air terminals.
