Dodecahedron: This part demonstrates the use of sketch relations to calculate angles and vertices. The solution to modeling a dodecahedron is surprisingly simple and elegant. Modeling a dodecahedron looks like it should be a complicated task involving creating multiple planes and features, but it can be accomplished with just a boss extrude and a cut extrude!
Features: Boss Extrude, Cut Extrude
