Hi Mareike -- A "geodesic" won't be much of a paraabola (except in the grossest of terms). A tue parabola has the (general) equation of X, AX²+B. Figuring out what your needed values of "A" and "B" will be the hardest part of the problem. Turning the resulting parabola into a "Geodesic" depends on the required overall accuracy. ??? -- LewI need some guidance on how to create a parabolic dish sing alibre script.
On the 'old' WIZO script website there was a paraboluic script and that is where I am looking forHi Mareike -- A "geodesic" won't be much of a paraabola (except in the grossest of terms).

Hi Stefan -- Either of your references get a parabola drawn -- but turnung it into a geodesic is a different issue. -- Lew
and therefor i have recommended to search forbut turnung it into a geodesic is a different issue

Hi Stephan -- I admit that I often complain about the "inaccuracies" implicit in using a nominal cubic spline to approximate a (say) parabolic or (say) involute entity. A Wronskian curve creates a "better fit" for many such entities. This is a different (and much more complicated discussion) than answering Mareike's question. -- Lewyou can trust me, i really know that, but i only want to point that you both have been disscussing about parabolic splines...
