more step-by-step constructions on conics and tangents are available here.
The webpage concerning the convex semiregular polyhedra includes tutorials meant to show how to model: the truncated tetrahedron from the regular tetrahedron; the truncated cube from the cube; the truncated octahedron from the regular octahedron; the truncated octahedron from the cube. (more coming soon)
The webpage with tutorials on how to model the cuboctahedron and the icosidodecahedron is finished and may be found in the upper menu or here. Comments and suggestions are always welcomed.
