Advantages of the
You will have a base perimeter of 18 sides instead
of 15. More places to anchor the dome.
Unlike the conventional pentagon zenith dome, the
Edge Zenith dome does not have altered geometry (some strut lengths are
lengthened or shortened, making 10 odd triangle sizes on the lower
to provide for a level base perimeter. This means that only two basic
of triangles are required for covering. No
"3/8" or "5/8" "truncation plane".
It is a half dome or exact hemisphere, Height = Radius.
Hubs do not angle down or up as on the GD3 and GD3+Base Option. The
will lay flat on a foundation, giving better weight distribution, at 18
places, instead of 15.
You can have a 22 ft dome made from standard 8 ft
lumber and covered with minimal qty of 4 x 8 sheets. Less waste using
22 ft diameter size. It is an optimal size for cost saving and waste
although smaller and larger domes can be built also.
cupola would be a diamond shape similar to the
Add -X1 Subdivision for larger or
