how to drawing a parabola in autocad ? AutoCAD does not support parabolas. You would need to download an AutoLISP routine or approximate the parabola with it's geometric equation and a spline. The downside to an AutoLISP routine is that you do not know how good it is and it might not play nice with other commands.
if you want "pure" parabola use a polyline ant then fit it with spline 2-nd order. You can also do the same using a spline object - 2-nd order too.If you can run lisp programs - I can give you one. It draws a parabola passing through 3 points you select.
