A while back I needed some regular shapes for exercises in FreeCAD
I ended up writing macros. With them you can build them in a chosen size.
- Piramids: full of knotted
- Polyhedrons : tetrahedron, hexahedron, octahedron, dodecahedron, icosahedron and truncated icosahedron
You can find these macro's on : https://github.com/eddyverl/FreeCad-Pyr ... olyhedrons
