A first vZome model explains the construction. Consider an inner dodecahedron (magenta), concentric with an outer truncated dodecahedron (teal). A rhombicosidodecahedron (green) intersects the truncated dodecahedron along a decagonal face. The solid intersection is a pentagonal cupola, Johnson solid J5). Its pentagonal face connects to a face of the dodecahedron by a pentagonal antiprism.

The second vZome model presents the Zometool building instructions, starting from a dodecahedron. The Zometool model is easier to build than its Geomag counterpart. However, due to the lack of panels, it is aesthetically inferior.

Drilled Truncated Dodecahedron

This model, originally designed by Karl Horton (https://www.flickr.com/photos/karlhorton/albums/72157603248361831/), is a famous model among geomag/supermag builders, because it requires both geomag and supermag rods:

  1. Square panels are required for stability. These can only be held in place if they are clamped between at least two geomag rods.
  2. Some edges meet at a sharp angle with a vertex, and that can only be achieved with supermag rods, not with geomag rods. </ol>
