Jason,
As of Right now there are no MVparts in my drawing alls that is in the drawing is round, rect. and flexible ductwork. I however do have quite a few 2d block that I have always used in the drawing, and architectural background xref (saved in ADT 3.3 only using ACAD entities), and a title block that is Xrefed. I have performed audits on the base drawing and the two xrefs to no avail. The underlying functions of ABS still work (duct, pipe, schematic pipe) when I can get into the drawing, however it is very annoying when it says do you really want to do this Y/N
Please help
