Okay, some of my elements are locked, but how can I unlock them if I can't see which doors are problematic in a 3D window?
Open a 3D view.
Turn all the layers on that have doors in them.
Then issue the 'Unlock All' command in the Edit menu or with the tool bar button if you have one.
This is assuming you have teamwork permission to unlock them (I don't use teamwork so not exactly sure what you have to do there).
