OK, the 5 regular solids from middle school geometry: Tetrahedron, Cube, Octahedron, Dodecahedron, Icosahedron All are drawn with 12" edge length, so scalable in feet. Fun, but not so easy to draw in VWX (except the cube). Folding to correct angle requires a trick. Anyway, use em if you need em.   Edit 08/07/17 Here's wikipedia info about these shapes https://en.wikipedia.org/wiki/Platonic_solid   v2017 file added -B
