I stupidly used a face instead of a plane when creating a mirrored part. The original part changed somewhat drastically, and now the mirrored part can no longer find the face. I can't seem to find a way to fix it. It wouldn't be an issue if the mirrored part hadn't already been checked into the pdm vault. Any suggestions on how to just point it to a plane to fix it, or do I need to create a new one?
