Re: Drawing a Parabola ?

Jeff and all,
Thankyou very much for your help. Jeff sent a Lisp file to me
and it's just what the doctor ordered. Generates the parabola
perfectly in a polyline form (not the dreaded spline) that only
needs exploding to seperate entities for g-code in a snap.
I will be, hopefully, machining a reflector for a miniature
locomotive on a temporary lathe CNC setup.
Borrowed plastic flashlight units can't stand the
heat above the boiler.
