Equation of a Parabola offset.

[mikes]

Hello there,

I created a parabolic surface (I know the equation, focal point, directrix).

Question : When I offset this surface with a certain amount, what would be the equation of the new parabolic surface (or the 2D parabola) created this way ?



TIA,

Michael

zero at focal point! Are you doing a radar dome or you have a radar dome model created?
