Modeling and Unrolling Dymaxion
Buckminster Fuller used the term “dymaxion” for a variety of his designs, and one of these was the dymaxion map. It was based on the geometry of a polyhedron. While the dymaxion map is more directly related to the icosahedron, Fuller’s work often involved using other polyhedral shapes. One of them is the cuboctahedron. He used this term for various conceptual and practical designs, particularly in the context of his ideas on efficiency and structure. The cuboctahedron itself is notable for its dual relationship with the icosidodecahedron. It is considered a geometric shape with balanced symmetry. Fuller used these shapes to explore ideas about the structure of space and the design of efficient, modular systems. In this short tutorial video, I am modeling and unrolling dymaxion (cuboctahedron).
This video series showcases various in-class exercises I conducted in a freshman-year Architectural Geometry course. Using Rhinoceros software, we explore Euclidean constructions, basic drawing and transformation commands, fundamental fractals, regular and semi-regular tessellations, patterns, and modeling techniques, including unrolling polyhedra. These short drawing exercises are also beneficial for junior-level architects, interior designers, industrial designers, and enthusiasts from other disciplines. I will be publishing exercises each week on my blog and other platforms. Here is the modeling and unrolling of dymaxion, cuboctahedron.
The software used in this course is Rhinoceros 3d (www.rhino3d.com).

Modeling and Unrolling Mecon

The truncated octahedron is an Archimedean solid, characterized by a mix of hexagonal and square faces, and it has a very symmetrical and regular structure. Buckminster Fuller called this solid “Mecon”. The truncation process includes the cutting the edges of a polyhedron. We do this by dividing every edge of the polyhedron into 1/3s. Then, we carefully re-connect these division points to generate new, planar polygons. In the case of a truncated octahedron, we transform the 8 regular triangular faces…
Modeling and Unrolling Buckyball
December 14, 2024
A Buckyball, (or Fullerene), is a molecule of 60 carbon atoms with a structure resembling a soccer ball. It is a specific type of fullerene, often referred to as C60, where the carbon atoms form a series of pentagons and hexagons in a pattern that creates a spherical shape. This structure is similar to the arrangement found in a truncated icosahedron, with 12 pentagonal and 20 hexagonal faces. The buckyball is named after architect Buckminster Fuller, who popularized geodesic domes,…
Modeling the Buckyball

The Truncated Icosahedron (5,6,6) is an Archimedean Solid we often recognize as the iconic soccer ball. This geometric structure, also affectionately known as the “Buckyball” in honor of the visionary architect Buckminster Fuller, has gained significant popularity and recognition both within the realms of mathematics and everyday life. It is composed of twelve regular pentagons and twenty regular hexagons. This symmetrical nature makes it an interesting object of study in geometry and various fields. This is a short Rhinoceros tutorial…
Folding Truncated Cuboctahedron

A truncated cuboctahedron is an Archimedean solid, meaning it is a highly symmetrical, convex polyhedron with identical vertices and faces of regular polygons. As its name suggests, you can create the truncated cuboctahedron by truncating (cutting off) the vertices of a cuboctahedron. A cuboctahedron is a rectified cube. After you model it, you can divide all its edges into 1/3s. Then, connect those division points to draw the squares, hexagons, and octagons. In this short tutorial video, I am folding…
Modeling and Unrolling Icosidodecahedron

An icosidodecahedron is a polyhedron that is part of the family of Archimedean solids. It has 32 faces, consisting of 12 regular pentagonal faces of a dodecahedron and 20 regular triangular faces of an icosahedron. It is highly symmetrical, with the same arrangement of faces around each vertex. In this short tutorial video, I am modeling and unrolling an icosidodecahedron. This polyhedron is very interesting and is mostly used as a basis for more sophisticated designs. Its dual polyhedron is a rhombic triacontahedron,…
