Dome -X Files. These dome model 1/5 sections
are more accurate representations of the "-X2" and "-X3" subdivisions of
the Garden Dome 3. Please refer to the Garden
Dome 3 model plans for details on making the paper models.
"X2" struts- divides the face planes of the dome into 3 triangles,
using a central hub in each. If you can visualize 3 dimensionally, you
can see the possibilities of a dome covered with diamonds; or pyramids,
depending on how you look at it. Compare with Casa
Manana and Epcot.
"X3" struts- divides the dome triangles into 6 right angle triangles.
It's easier to cover a dome with right triangles since you are working
with rectangle sheets such as 4 ft x 8 ft.
On a more simple dome, the X2 struts simply add triangles for increased
structure for a stronger dome and more struts for attaching roofing.
For a greenhouse this means you can have a large dome that's easier
to cover- triangles large enough to let plenty of light in but small enough
for convenient covering.
For covering with roof decking this means more substructure for nailing
on panels, without having to deal with lots of miters and bevels and different
You can see with this dome by making the inner triangle hubs at a smaller
or larger radius, a pyramid truss can be acheived that give an interconnected
double 3D grid - "space frame."

best results use a photocopier (or printer) to copy 5 times with thick,
colored paper. You may use for non commercial purposes as an educational
demonstration for domes that can be built large scale using the products
