I would like to create a solid of revolution but do not know how to do it.

Some background:

(Solids of revolution are a topic usually covered in Calculus 100, first year university.)

A right cone can be considered a solid of revolution

created by revolving the straight line, say, y = 100 - 1.272x around the y axis.

In Sketchup, a right cone can be created easily enough.

I would now like to generalize to other curves that get revolved around the y axis. As a first step, say that instead of a straight line, I have a parabola that gets revolved: y = 100 - 1.272x^2

How do I do this in Sketchup?
