Parapet Audit · Free · Revit 2020-2027

Find every DWG hiding
in your model.

Imported CAD is the #1 cause of slow, heavy, unpredictable Revit files. Parapet Audit lists every imported and linked DWG, shows which views it appears in, and lets you clean up with confidence - free, forever.

No license key, no trial, no account. Just install.

See everything

Imports, links, nested imports in families, their symbols and instance counts - in one list, sorted by weight.

Trace usage

For each CAD file: which views show it, which are hidden, which sheets it ends up on. Jump to any view in one click.

Clean up safely

Select, isolate, or delete with a confirmation that lists exactly what goes. One transaction, one undo.

A Revit model with DWG imports hidden in views, nested in families and on the wrong workset - and the Parapet Audit list that exposes them.

Every Revit user should be able to find out what's bloating their model. Audit is our introduction: it gets the Parapet tab into your ribbon and shows how we build things. If you like it, Hub and Link are one click away in the same installer.
