R8 Issue with Clipping Sections, GPU Tessellation, and Wireframe Display

Hi Wim,
Thanks for the comprehensive reply!

Yes it does, and I’m not sure if I submitted a report when the crashes happened. They happened so often that I was really just try to rush to find a patch and didn’t think to log details to forward. The only reason it came up is because the wireframe visibility is very difficult to work with, and staff member today was having a particularly difficult time.

I’ll be sure to submit a crash report next time it happens.

You’re absolutely right; I failed to mention that the templates we work with are somewhat robust and to say ‘model of any size’ is inaccurate. To better drill down on at what threshold Rhino ceases to work I’ll try a few test models with GPU Tessellation turned back on to see if I can replicate the problem. It’s a bit of a toss up where and when the crash happens, but without a doubt even a single clipping section will cause R8 to chug.

Just updated, but here is my systeminfo.
