Hey this is my first forum entry so if i did something wrong pls tell me. I want to make a solar trough. And i would like to cut out the basic shape of the parabola in wood and i want to have a near perfect shape ( so that all the light if as focused as possible) so i thought why not make a sketch and print it out. But i want the parabola to have an underlying mathematical function ( e.g. y=0.0016*x^2) but i dont know how to do it in any program i have accesses to, autocad for mac ,inventor fusion for mac and a solid edge st3 but im not very familiar with the last.All help is greatly appreciated.

Hello, you should read the TIPS :
N° 6606 ( direct link just here under ) : How to crete geometry from Excel.
N° 8479 : How to generate 3D surfaces from mathematic expression.
I hope that you will suceed with your AutoCAD for Mac.
Please tell us if and also how you suceeded or not.

hi,guy,first,you should know this below :

rappelzdzd, what are you trying to do by repeating all the sentences that you can read ?
At least you could have corrected my grammatical errors ( crete --> create ).
