As far as I know the ONYL way to do this (define a bezier spline) is 
with a set of early macros written by Chris Colefax and put into an 
include file called spline.inc

The macros are very powerful allowing you to use control points for each 
point on the sline.


Also as far as I know no one ever duplicated or modernized his work 
(which surprises me)

It resided on a geocities site and I note that there is an effort to 
preserve early POV contributions which resided there even as we speak. 
The thread is in p.general

I do have a copy of those (very useful) macros if you cannot get it any 
other way.
