I guess my understanding of NURBS isn’t as good as I thought. So how do you have a surface that has a degree on 1 in the U and V direction, but isn’t planer? If I run the command IsPlaneSurface() in python it returns false.
I can see where a surface could have a degree of 1 in one direction but not the other not being planer, like a helix. My thinking is that if it’s a staight line in both direction it would have to be planer. What am I missing?
