The Icosa Dome developed into the Zome
The Icosa (brown) and Dodeca (purple “X3” struts) merged:
The shallow pyramids in the Icosa faces. These are the “X2” struts. Zome faces are created.
X2 and X3 struts, pushed out to make the shallow pyramids and Zome faces. Result is a reinforced Icosa Dome-Zome with large flat parallelogram faces that can be covered with less angles in cover panels, less cover panel seams, possibility of using the Vertical Riser VBO (“Vertical Base Option”), larger domes, orientation variations such as the EZ Zome, etc.
