Icosa Zome Orientations
Three orientations are shown with profile and pictorial views.
1. 5-way connection is at top
2. Edge (strut) and parallelogram Face is on top. Front and back openings are created. Four adjacent faces are extended up to make a pyramidal top that will shed rain/snow.
3. 3-way connection at top makes a zome with 3-way symmetry. Bottom triangles are shortened to provide a flat, level zome.
