Mesh problem

yes that s a promising apporach…seams to work here.

and please before others dig in:
start grasshopper with disabled solver.
the current definition needs at least 2 plugins and generates a ugly amount of small / short curves, and uses pipe and mesh intersection … will compute depending on your hardware … but not fast at all.

or wait till @Ömer_Ekici provides a minimal version to repeat his issue.
