Here we have the modified triangles
with Base Option on a 2" x 2" frame, 12 ft diameter.
Framing for the entrance is on the same vertical plane as the adjacent
triangle.
Height of the Base is same as one of the large triangles. This makes
the opening of the 12 ft dome about 40" x 60".
Pentagon centers are pushed out to make the vertical
triangle. In this example, all pentagons including the top
are given this treament.
