There are a variety of 3D solids (polyhedra) that can be fit together to build more complex objects. These polyhedra that can be fit together to form other solid shapes indefinitely are considered space filling polyhedra.

Think 3D allows you to examine and build with many of these space filling polyhedra. Think 3D takes care of all the details, you simply tap to add a solid, drag one finger to rotate your creation.

Tapping the face of any solid will attach another solid to that face. Use the + and - buttons to switch between adding and removing solids.
