What does "THIS DRAWING CONTAINS OBJECTS THAT EXCEED THE SIZE LIMITS FOR LEGACY DRAWING FORMATS" mean?
What is a LEGACY DRAWING?
I created a drawing using a 64 bit computer loaded with AutoCAD Civil 3D 2012 several weeks ago, I just tried to open the the drawing set for review markups and I get this warning that "THIS DRAWING CONTAINS OBJECTS THAT EXCEED THE SIZE LIMITS FOR LEGACY DRAWING FORMATS". Now I can't get into the drawings and AutoCAD keeps crashing and closing. I an a RECOVER and AUDIT but that did not work. My ISAVEPERCENT is set to zero ans so is my LARGEOBJECTSUPPORT option. Sheet Set Manager and plotting does not respond either.
