Goal: to get a crease in the SubD of a surface based on splines repeating these edges.
I create a Low Poly object in 3ds Max and create splines along crease edges in the same place.
I export all this to Rhino, convert the object to Sub D, and I need to use a script or a grasshopper to select the edges that lie in these crease splines.
Where to dig? And is it even real?
