How can I achieve this entirely in c# only! Using no grasshopper components or just using slider as inputs! drop.gh (24.8 KB) [2023-03-27 05_47_25-Settings]

Most of the time it is degenerate faces, so something like mesh.Faces.CullDegenerateFaces() is enough. So with healing it works, here a component from Nautilus plugin (I must change it as sometime rhino says the mesh is valid but it has degenerate faces !!) [image]

Query grasshopper

Grasshopper
