Modeling and Unrolling Icosidodecahedron

An icosidodecahedron is a polyhedron[1] that is part of the family of Archimedean solids[2]. It has 32 faces, consisting of 12 regular pentagonal faces of a dodecahedron[3] and 20 regular triangular faces of an icosahedron[4]. 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[5] is a rhombic triacontahedron, a Catalan solid[6]. I especially love this Catalan solid because of its rhombic appearance. This is why, the icosidodecahedon is a good starting point to create a model of that.

I have been conducting a series of in-class exercises in the freshmen year architectural geometry course, focusing on Euclidean constructions, basic drawing and transformation commands, introductory fractals, regular and semi-regular tessellations, patterns, modeling, and unrolling polyhedra using Rhinoceros software. Junior architects, interior designers, industrial designers, and enthusiasts from other disciplines can benefit from these concise drawing exercises. I will publish exercises every week on my blog and other platforms. So, today’s exercise is modeling and unrolling an icosidodecahedron.

The software used in this course is Rhinoceros 3d (www.rhino3d.com[7]).
