When you open a Revit project file, you can set options to audit the file for corrupt elements, detach the local model from a central workshared model, or create a new local copy of the central model.
Click Open (Project).
In the Open dialog, navigate to the folder where the Revit project file resides.
To see only files of a certain type, select that type from the Files of type drop-down list.
Select the desired options:
Audit: Scans, detects, and fixes corrupt elements in the project. This option can greatly increase the time required to open files. Use this option only for periodic maintenance of large workshared files or when you are preparing to upgrade.
