Wow. It's been quite a while since I was able to open up a new program and immediately use it. Absolutely brilliant bit of UI work here. I ran into a problem earlier and sent a bug report your way. Weird fillet issue. Also, am I missing the "project curve" type tool, or is this feature not implemented yet?

Maybe it's just me, but I get the feeling this could be the NURBS equivalent of Silo.
