This sample builds a model of a "Shell" tlp. This one generates a model for URSA, but the data is defined in terms of a few parameters and has also been used for MARS.

To change the geometry, simple change the dimesions at the beginning of the file. If you get errors, you may need to change the dimesions slightly to avoid having lines intersect.
