I'm trying to generate a path grid for a room I made and when I do the Construction Set crashes. Nothing to the room really just a few chests, bed, sound emitter, painting, and door. I have the latest version I believe (1.2.0.404).

Anyone have an idea?

Unfortunately, you can't "generate" a pathgrid for an interior. You have to set it up manually. There's a brief explanation on how to set them up http://cs.elderscrolls.com/constwiki/index.php/Category:Path_Grids

http://tesalliance.org/forums/index.php?/forum/82-esiv-oblivion-school/ has a much better tutorial on doing path grids. Unfortunately it's buried in the CS Basics courses, but the courses are a lot of fun to work through, so you might want to check them out. That CS page has a bit of misinformation.

That's a bummer. Don't think I'm going to waste my time doing it by hand for one little cell. Thanks for the links I guys. Already a lurker @ TESA for a while now and had that CS Wiki bookmarked. Didn't see anything on there about that option being busted before I posted. It will be a hoot watching companions trying to walk through tables though.
