Great work ! Thank you !

If you're looking for an idea for new feature, i've got a great one : Export as OpenSubdiv !

That means quads not tris, and nice shaped polys around booleans, so Turbosmooth / openSubdiv can work in polys 3D programs...

I'm quite sure it is impossible, but hey, you are the clever guy, i'm only the user one ;-)

Best regards
