Thanks @dale, I saw that one too and followed the link to RhinoPolyhedra. I thought I had already installed it but to be sure, I downloaded and installed it again. Restarted Rhino. But I’m lost in trying to use it or IcoSphere.
How do I invoke your plugins? Why is WatermanPolyhedron showing up when I have disabled it? (though as expected, I get this when I use it: “Unknown command: WatermanPolyhedron”) Where do ‘HugelPolyhedron’, ‘PentagonPolyhedron’ and ‘SchonhardtPolyhedron’ come from?
P.S. I found ‘MeshIcoSphere’ but again, can’t seem to control the number of faces or vertices?
