Cool, Michael.

I may have asked before, but is there some way to get the x,y,z value of the Normal Vector at point "p" on a NURBS face/surface?
The Normal could be at iso (u,v) intersection point. A line normal to a face can be manually found on screen...

(My current project is solid sweeps, but the math is very difficult, and scripting can only do so much by itself :-)
