fatal error: unhandled e06d7363h exception at 7c812aebh

I keep getting this error and my auto cad closes. I am working on 3d dwg done is MEP but im only making viewports. I did the first 5 viewports fine then on the 6th one this happened. On another comp it happend while making the first viewport any help would be great.

I'd recommend searching on the error message over at the AutoDesk Discussion Groups as you are not alone in seeing this particular warning. I'd also suggest checking the AUGI forums as well. You may have to take a trial and error approach to resolving your problem as various "fixes" have been proposed depending on what action precipitated the error in the first place. Good luck. Please let us know the outcome.
