    Hi,

    I am in need of a lisp function to draw a parabola. The function is y=squareroot(4px). I envision the inputs to be p, the max value for x (the min value is always zero) and the x increment. Does anyone have something that would work for this in ACAD Version 12? Any help is gratefully accepted.

    Attached is a file that has a function called graphfx. The catenary function calls it to draw the catenary function and shows you how to call the function. Just substitute your parabola function.
