awesome. thanks for that info. i've been really curious to know. yeah parasolid and acis do give off a big business vibe for sure. that's why i stay away from their software as well. one interesting thing is parasolid and acis both started from the same group of guys from the uk. so it's rather hard to know what exactly are the pros and cons of each. agree with you on the russian kernel as well. even before the war that sort of thing is a concern for me. i imagine they have the same feelings, so that's why they have their own kernel.

i hope the acis kernel works out. this really makes moi stand out from rhino a lot more now. one huge disappointment with rhino is they keep adding stuff i have no interest in and keep leaving stuff broke or working poorly. the development time is also way too slow. if they would at least sell features in packages it would help a lot. so a lower price for just nurbs, more for subd, more for rendering, etc... they just seem happy to make one huge blob.
