Robert, I had one of our users asked if I'd seen crashes while doing a save as to get a STEP file. He was able to get a parasolid just not an IGES or STEP.
I'll keep an eye out. He and I both use the same K5000 video and our drivers are up to date.
I've also had some crashes while saving drawings to DWG.
SW 2015 is extremely unstable for me and I'm seeing some other posts saying the same about it. This is unfortunate for me since I have canceled my maintenance and I've chosen 2015 as my last version. I wish I stuck to 2014, it was running so well.

I second that
