allows you to make your own planar nets interactively, or to add tabs to any
of the nets provided as !PolyDraw data. You simply drag a data file to
!PolyNet on the iconbar which opens the 3D working window, you click on any
face and another 'net' window opens, keep clicking on faces connected to
one already in the net and you can make many different nets.
If you want to use the nets to print to card, cut it out and create a real 3D model then you can add gluing tabs and you own ideas of clip-art to the faces. You can make pretty boxes for a friend's birthday present or boxes for special occasions such as Christmas or Easter.

The process of stellation is explained here for the example of a regular Dodecahedron.
!Stellate is supplied with data to make more than 120 polyhedra,
including all the 'Uniform Polyhedra' with their Duals and is able to make
all their Stellations. Use these as starting points to create your own
entirely new polyhedra. The package has extensive documentation, including
a glossary of terms and a set of suggested activities to help you learn
about stellations and their properties, a few explanations and diagrams can
be seen here.

A 'Uniform Polyhedron' has faces made of regular polygons with the same types of polygons arranged in the same order around all vertices. In his book 'Polyhedron Models' (Tarquin Press) Wenninger has arranged these in increasing complexity:

Click here to see polyhedra from 64 to 119
and a few extra ones we particularly like (103Kb)
Click here to see the duals (74K)
of the non-convex uniform solids made by !Stellate.
( The dual of a uniform solid is the one where there are faces in the directions of the original's vertices and vertices in the directions of the original's faces.)
