I have some 2004 3D drawings created in vanilla 2004 and saved as 2004 version DWG's.
I can open them using AutoCAD 2004. But when I try to open them in AutoCAD MEP 2008 the drawing begins to open and the progress bar at the bottom of the screen reaches 93% and it hangs (not responding).
This also happens when try to use Recover to open it. It shows no errors and then hangs.
I have also tried using DWG True View with the same results.
Any ideas?
I tried to search for other posts that might address this but was told by the Forum Serch Engine that "2004 3D Drawings opened in 2008" is too short of a term must have a minimum of 3 terms.
