After the geometry has been set, we need to divide the geometry into several subdivisions, called elements.

NextFirst, we need to enter the number of divisions for each side. This specifies the number of elements that will be created along each side. Opposite sides need to have an equal number of divisions. So, in the above schematic of vertex positions, sides 1 and 3 should have an equal number of divisions as should sides 2 and 4. (Notice that sides are numbered in the same counterclockwise order as vertices, starting at the first vertex.) We'll use 6 divisions for each side. So enter 6 for Side 1-3 divs as well as Side 2-4 divs (see figure below).
