Hello folks,
I received a drawing which had a digital signature, and I get a ".dwg is currently in use or is read-only" upon opening. I saved a copy of this drawing with a new name and made a bunch of changes, added layers etc.
When I open this drawing now, I don't get any of the messages I mentioned (read-only, signed), and everything I have done in paper space remains as it was before I closed it. However, all of the model space data is missing, gone. If I copy objects from the original version into my new saved version, it comes in just fine. I've tried opening with Civil, regular CAD, restarted my computer... nothing seems to work.
Any ideas?
Thanks!
