I have had some issues with annotation being deleted from the saved drawings.
it has happened more than once and dimensions have been deleted in one case and MLeaders in another separate drawing.
I rename the bak dwg and open it, the diemnsions ( and or) MLeaders are still there.
Aside...the dwgs are originally exports from 12D software....dont know if that has something to do with it...
the problems are random and others using the same software and using 12D exports dont seem to be experiencing the same problems...
hope someone can help me...
cheers
