We have a part file that was created as a mirrored part. The original file and the derived file are both in the vault. The original file is fine, but the mirrored part is empty, that is there is no geometry present.
The mirrored part was checked in and transistioned through the workflow, so there are two versions of the file in the vault, however both versions of the file are empty. So basically, there is no physical geometry at any stage of this part's history. I could dismiss this as user error, however there is a drawing of the derived part showing the geometry on preview, but when the drawing fully opens, the geometry dissappears.
I have search the SQL and File servers, but the file integrity seems fine. Any ideas or anything more I can check?
This file can be rebuilt relatively easily, but I would still like to know what could have caused this.
