Unfortunately, Rhino is a nurbs modeler. When it converts to meshes it does a polar division into squares that get smaller towards the north and south poles of the sphere. There is the ability to generate a mesh sphere but it always has 1800 polys. I have found a neat little program called WinDome for generating geodesic domes, either surfaces or wireframes. It will generate class 1 or 2 domes with Ichosahedral, tetrahedral, or octahedral structure. It will do true spheres, eliptical or parabolic domes. Output is in dxf vrml pov or ascii 3 cordinate points.
