I have created a DWG file using a non Autodesk 3D modelling program and opened it into LT08. (The file is 2D) Usually this doesnt cause any problems, but this particular file is not allowing me to copy (using copy and paste) from the original to a standard template we use.
It gives the error message:-
** undefined block #-1
Any one have any idea what this means?
I have purged audited/recovered the file, saved back to '04 '00 and still no different.
Regards
