I get the following message and instantly booted out; "fatal error unhandled c000000dh exception at 7303fac3h" any suggestions on how to fix the problem? All other files are fine.
There are several methods how to try to open a corrupted AutoCAD drawing file.
• Use the Recover command
• Open the file and press ESC key just before Regeneration/Error message, save to DXF, load, save as DWG, Audit
• Insert the complaining DWG as a block into an empty drawing
• Open/save the DWG in an older version of AutoCAD or AutoCAD LT or Actrix
Take a look on following useful resources and knowledge bases:
As mentioned above, other dwg based programs may be "less picky" or more tolerant, Bricscad for instance.
Rhino is very tolerant and will often open (import) the file, but then you have import/export issues.
