2013 crashes on this one drawing file

[David Nisbet]

Everytime I start nxt it crashes autocad on this file. Any suggestions?

Thanks,

[David Nisbet]

I found a fix to the problem. This drawing had 3d solids exported from Revit and 3d blocks imported from Autocad 2012 which were from a previous Nxt rendering. Opening the materials browser in Autocad 2013 and deleting the Accurender:white material then purging the drawing resolved the issue.

I will check out your drawing when I get a chance.  This is likely a known issue which has to do with AutoCAD versioning.  It may be important to have nXt loaded when passing nXt data around.
