If you specify the same value for both the base radius and the top radius, then
a cylindrical helix is created. By default, the top radius is set to the same value
as the base radius. You cannot specify 0 for both the base radius and top radius.
If you specify different values for the top radius and the base radius, then a
conical helix is created.
If you specify a height value of 0, then a flat, 2D spiral is created.
NOTE A helix is a spline approximation of a real helix. Length values may not be
completely accurate. However, when you use a helix as a sweep path, the resulting
values will be accurate regardless of the approximation.
