Line 17:

An alternative way for [[polyhedral compound]] models is to use a different colour for each polyhedron component.

Net templates are then made. One way is to copy templates from a polyhedron-making book, such as [[Magnus Wenninger]]'s ''[[List of Wenninger polyhedron models|Polyhedron Models]]'', 1974 ({{ISBN |0-521-09859-9}}). A second way is drawing faces on paper or with [[computer-aided design]] software and then drawing on them the polyhedron's [[Edge (geometry)|edge]]s. The exposed nets of the faces are then traced or printed on template material. A third way is using the software named ''[[Stella (software)|Stella]]'' to print nets.

A model, particularly a large one, may require another polyhedron as its inner structure or as a construction mold. A suitable inner structure prevents the model from collapsing from age or stress.

==Interactive computer models==

Recent [[computer graphics]] technologies allow people to rotate 3D polyhedron models on a computer video screen in all three dimensions. Recent technologies even provide shadows and [[texture (computer graphics)|textures]] for a more realistic effect.
