Are yout talking about getting an curve you can sweep around or what?

What is your goal I can get you a curve from I-Deas with these numbers

I think you can set up law curver in UG to get this type of curve

Also Can you do a revolve with translate with a change in radius

Law curves is definitely the way to do this.

Hint: t is your variable, its range is 0 to 1, divided into increments.
