I get this message "ERROR in DeepCloneXlation:eWasErased" when I try to copy and paste items from one drawing file to another, only in CADWorx. It does not happen in plain AutoCAD. I had the problem and finally fixed it by replacing my CadworxPlant.arx file, but the problem recurred and I can't seem to fix it this time. I have current object enablers loaded. Does anyone have any insight into this issue? thanks!
I should also mention that I'm not able to WBlock or anything that copies entities out of the drawing.
