Is there an easy workflow or some components I should look at if I want to convert a nurbs polyhedron to a mesh, preserving the faces without triangulation? For example, a geodesic sphere with hex and pentagon faces. Or is there a way to do this with any polysurface with all linear edges, regardle…

For planar nGons you can use this one-liner: [image] ghAddNgons.gh (5.1 KB)

Hi @Max3 , _ToSubD respects nGons present in the input mesh, so if you mesh your brep and run _AddNgonsToMesh before converting to subd it should work for all planar faces no matter the vertex count (hex, penta) Edit: Just tested, it also works with non-planar nGons [image] SubDNonPlanarNgons.3…

Thanks. I just tried it in Rhino and it worked great. Is there a grasshopper component that is the equivalent to _AddNgonsToMesh?

Thanks! This should be a standard component. (please? @DavidRutten )
