modeling a formula ?

I need to an equation in autocad. Rather i want to.we have not covered this in class yet and probably wont be covering it. I want to model the equation for a Von Karmen profile nose cone. This may be something that cannot be explained through this forum but i thought i would ask anyway. I have step by step instructions for a program called PRO/Desktop (?) I was going to try and adapt those instructions to autocad, but I'll be the first to admit it, I'm not that smart. Any guidence would be greatly appreciated. Please feel free to move this to the appropriote forum if this is the wrong one.

I suspect you would need to run a Lisp to do this. Lee Mac and Seant or Fuccaro would be (from memory) the guy's who would be best placed to offer guidance. I just did a search for "Parabola" and there are a few posts on the subject but none (that I recognized) would be a firm solution, have a look yourself as I am always struck dumb when math formula are presented to me....I'm probably less smart than you! Good luck in your search.

Use the formula in excel or a table, have it produce the results in coordinates, run those in AutoCAD as a script.

You could simply calculate the enough point to satisfy yourself and plot these points and draw spline across the points.

You might add parametric dimensions if you want to edit in the future.

I think I would be learning a modern program like Autodesk Inventor for something like this.
