I had seen RhinoPolyhedra and just installed IcoSphere but a) these are Rhino commands, not GH(?) and b) no matter what I try, including MeshIcoSphere, I can’t seem to set the number of sides? I don’t know how to get IcoSphere to work at all?
I also saw the LunchBox Platonic Icosahedron but it implies 20 sides, fixed, not polyhedron?
I squandered more time investigating a C# component I found here, in a model by @laurent_delrieu :
It looked promising but the C# code looks sketchy and produces output in steps, as ‘nfaces’ ranges from 1 to one hundred thousand(!), the actual number of mesh faces are 20, 80, 320, 1280, 5120, 20480 or 81920. Weird.
This part must be a very common GH question, so why is the answer so hard to find?
