Small update: I haven't been able to explore all of the details, but I did look into Sebastian's response. Although the preview was great and the rendering didn't cause errors, it did still fail to render (would render "complete" after 15 minutes without actual data in the file. I tried forcing goldfeather, and I also tried two different computers (the second computer, with more ram and better graphics card, would get a C++ runtime library error crash.). But what ultimately worked was using MeshMixer to reduce the triangle count by 85% (from a 12mb STL import to a <2mb STL import.) I now understand that it's understood that oscad can't handle larger STLs very well (I did not understand this.) According to a few forum posts, anyway. Is there anything I may have been able to do or setup differently to allow it to handle the 12mb version? A point of curiosity, since the 2mb version was of plenty detail. ᐧ On Wed, Aug 17, 2016 at 1:54 PM, Tomek Brzezinski <brz.tomek@gmail.com> wrote: > Thanks All!
