It seems as if I work on a drawing long enough it wil become damaged. I always keep a back up copy going after learning the hard way, but it is quite frustrating. I came into the office today and when I tried to open the drawing I am working on, I got the "file is damaged,will attempt to open with as much data as possible." (I am working with VW11.5) Does anyone else have this problem? Solutions? Suggestions? Thank you in advance.
