Crash when typing NXT

[Chris Fox]

This is the second time this has happened.  I will be working on a model then when I type NXT I get this AutoCad crash "FATAL ERROR: Unhandled Access Violation Reading 0x0000 Exception at de241c2h". I have tried purging and running audit but to no avail. If I try opening the drawing with an NXT running the drawing will crash prior to opening.  I am attaching the drawing

Thank you!

Somehow the material called AccuRender-Glass got hosed.  It's unassigned, so you can easily purge it.  (The material called AccuRender-Glass-01 is fine.)  Purge it before you load nXt-- then load nXt.  You should be good to go.  If you can't figure it out I can send you a corrected version of your drawing.  Let me know.

This sort of thing normally occurs when you switch file versions without nXt loaded.  There may be some other ways to make it happen-- such as loading a version of a block with nXt data when nXt is not present.

Quick Question.... if the material had been assigned to an object. How would know what one it is?

Select object -> look in the Properties panel (Ctrl+1), there is a material assignment line somewhere.
