If you can't tell, already, I'm enamored of geodesic constructs. It is my hope that these deviations will inspire others.

Curved-Fold Cardboard Geodesic Dome
Geodesic dome, composed of curved-fold cardboard struts • See original dome, at the link:
srchlab - Curved-Fold-Dome
(Plenty of photos)
Original dome diameter: 7 meters • Such a dome can be made, instead, of sheet metal, assembled with pop-rivets
SketchUp 3D model available • 3D Warehouse: Curved-Fold Cardboard Geodesic Dome • Patterns for struts included • Four strut definitions • The design of the strut "end flaps" allows for construction without hubs

Starweave - Icosa
Geodesic weave • Icosahedron symmetry • Geodesic class: I • Frequency: 1v • Simplest of the icosahedral "starweaves" • Only two different segment lengths required • All segments lie on "great circles"

I had not seen your study, but I do, personally, take full advantage of components (as opposed to groups,) because of the file-size savings.
It should be common knowledge, since it's in the "SketchUp Users Guide," but many don't read it (or, even, know about it.)
-Taff
Yup, I didn't know about it. Thanks
The only convex polyhedra that can be constructed of equilateral triangles are the tetrahedron, octahedron and icosahedron. To produce greater complexity (and more-closely approximate a sphere,) irregular triangles must be introduced. If the solid surface is allowed both, concave and convex regions, then Lobel frames, employing equilateral triangles, can be a (rather odd) solution:
3dwarehouse.sketchup.com/model…
I wasn't necessarily thinking of equilaterals and should have said fewer regular shapes. I think in years past I had found those tetra's, octa's and iso's but due to senility or an early case of alzheimer's I couldn't find any tutorials for the past couple of weeks, except that link I mentioned. More exactly, I was thinking of Epcot's Space Ship Earth which, in my mind's eye, I thought was made from two or three regular triangles reiterated to make a sphere. Imagine my embarrassment when I just looked it up (having only now remembered it's name) and found it actually has a lot of "fudging."
As a matter of fact, I think I just remembered a previous search for geodesic tutorials that I found by looking up "soccer ball" so I'll try that now...
My apologies if I was a bother and my thanks for your help.
