Classes of Domes   When using a geodesic dome calculator it does
all the math for you. But what’s really behind those results?
This page is a summary of mathematical classes used in geodesic
designs.   Icosahedron/Alternate (class I)  Octahedron/Triacon
(class II)  Tetrahedron (class III)  All subdivisions of class
I, II and III are based on the polyhedron.  Class I  (a.k.a
Alternate) is the most common subdivision used these days.
Almost all geodesic calculators on the web are based on this
class.  Class II (Octahedron/Triacon) was originally the
subdivision type used in the early days of geodesics, the one
Buckminster Fuller   the father of geodesics primarily used. You
will find references to this subdivision class in books such as
Domebook 1 and Domebook 2.  Class III (Tetrahedron) is rarely
used in designing geodesic domes.   What is important to
remember  For most who wish to build their own geodesic dome,
class I is almost exclusively used with geodesic dome
calculators.  Be Sociable, Share!
