3 frequency dome geometry taken from Dome Cookbook of Geodesic
David Kruschke, 1972. He was a contemporary of Buckminster Fuller and
worked with him on some of his later large dome construction projects.
Mr. Kruschke called us on the phone a few years ago and we talked a
long time about domes and Bucky. Very cool!
As can be seen from the side profile views, both the short ("3/8")
and tall ("5/8") domes have bottom vertices that are coplanar. That
the domes have bottom parts that will lay flat on the ground without
extra modification or alterations to the geometry (as presented in Hugh
Kenner's Geodesic Math). This makes the Kruschke dome an easier method
of building the 3 frequency dome.
Making the 3D wireframe into a pipe dome 3D model is a fairly easy
process using Turbocad 10+ Pro (must be the Pro version). Polylines are
given the fillet, then then pipe diameter is applied.
The 35 ft 2 x 6 version, illustrated with a spa / hot tub, brick
grill and two picnic tables.- a little more difficult to construct this
All triangles are isosceles,
allowing a perpendicular bisector, designated as the X1 subdivsdion.
