I’m very new to Rhino common and VB.net but I do have a lot of C programming experience.
I’m trying to pick a polysurface and find the intersection curve(s) with another planar surface. How do I do that? I managed to pick one surface and intersect it using Intersection.SurfaceSurface. That works great. I can also pick the polysurface but the intersection fails. Is there a trick to intersect a polysurface or do I first have to divide the polysurface into its component surfaces and then intersect one after the other?
