What shape is it supposed to be?
If it is supposed to be flat, try using a polygon object. Or maybe a 
prism object is what you are looking for. These are official version 
features.

If it is shaped like a pipe with varying radius, try using the 
sphere_sweep object, available in MegaPOV.
If you want to specify certain control points and use a spline to get 
the "in-between" positions, there are two spline patches available in 
MegaPOV.
