A while back I posted a question about methods in creating nurbs surfaces like a rectangle for example and now for my senior architectural design project I need to take it one step further. Without any pictures it might be hard to describe what I'm looking to do but when I get home I will post pictures of my prelim model. basically what im doing it creating a planar landscape with precision "slits" throughout to replicate icelandic greenroof houses with a modern twist. I have a nurbs surface created and the control points activated but now what i want to do it is actually use these lines to slit the nurbs surface creating new control points that i can use to morph the nurbs surface. Ive tried boolean operations but I cant seem to get the line to effectively slice the plane. I'm horrible at explaining things so I hope someone can understand and help me lol. Thanks everyone.
