Finding "normal" direction at intersection of a polyhedron

[Joseph_Oster]

I vaguely recall installing something related to polyhedra and located this post from three years ago:

Golf ball? Evenly spaced points on a sphere?

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 prod…

Referring to RhinoPolyhedra:

And this post in the same thread:

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. [plugins_2019Jul17a] [plugins_2019Jul17a2] [plugins_2019Jul17a3] 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 ‘HugelPol…

At the time, I had no luck trying to use it and believe it wasn’t related to Grasshopper. Now I’m wondering if anyone else can see the ‘Mesh | Polyhedra’ tab and run the code in my previous post?

Is this a standard R7 GH feature? Or visible only to me?
