Hi David, this is Drew from QA on LayOut. Would you mind sharing a copy of the file with me directly? If we have it in house we can run some diagnostics on it and hopefully tease out the error. This issue is nearly impossible for us to re-create from scratch. You mentioned that is has been occurring for some time for you. Do you recall the earliest version of LayOut you saw it on? Also, what type of machine are you using? Thanks David and I'm sorry for this frustrating issue. My email address is drew@sketchup.com if you'd like to talk directly or send a file.

All,
We've created a help article on SketchUp's website that will walk you through your options for beating this issue.

bmike,
This is Drew in QA on the LayOut team. I'd love to investigate the crash with you file---could shed a lot of light on it. PM me. Thanks and sorry bout the crashes

fionmacool,
What does the model look like in an image, exported directly from SketchUp? What are your OpenGL settings in SketchUp? Is hardware acceleration on or off? If you were to check or uncheck (whichever is different than what you had) the hardware acceleration setting in SketchUp and then send to LayOut, do you still see the problem? Thanks.
