I gave it a try with the sawteeth, but once I rotate the second set, I get weirdness, as shown in the attached pic. Also is a render of a sphere surrounded by Mighty Pete's Shape #1494, which is what I'm trying to get close to. The mesh is great, but I would like to have one with denser triangles. Thanks, joechip, for the link, but as you can see, I'm looking for something with a surface made up of triangles, and I want the structure of the dome --the struts.
