It is a very old problem. When we manually intersect two surfaces , where one is trimmed and other is a planner surface, we always get the curve on the trimmed visible surface.
But while doing automaton, I mean in grasshopper component as c# rhino-common, the resulting intersecting curves are going all along untrimmed bit of the surface.
This was a problem with Rhino 4 and 5 , if I am not wrong, or if I am not aware of how to get only the trimmed bit of the curve.
My question is how to get intersection curves only on trimmed bit of surface, so I do not need to do manual cleaning later on.
Please guide me how to get the intersection curve only for the trimmed bit of the surface, the part which we want to keep.
Many thanks in advance!
