You can apply a texture mapped material to either a 2D shape imported from
the 2D Shaper, or to a cube that has been scaled down to a wafer. All this
is covered in the documentation. I recommend reading Tutorial #11: Mapping.
Also, look in the Reference Manual at Surface/Mapping in chapter 7, and
Mapping in chapter 9. While you're at it, check out Create/Object/Get
Shape in chapter 7.
