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.
