Revit Error Message

[Anonymous]

Lately with our revit files I have gone to change something (shower pan width or wall connection) and when I try to make these changes I get this error.

Does anyone have any insight on why this is happening?

Thanks!

Possibly an error within the family you're editing.  The next time you open the file, check the "Audit" box and see if the error continues to occur.

What does the audit function do?
