Amapi question

How do I revolve, lathe or spin(whatever you call it) in Amapi 4.

1st, draw a circle
2nd, extrude it
I know it’s not in the usual way, but when you know that you can increase/decrease the number of vertices in the circle with “+” and “-” keys during creation of the circle and you can also increase/decrease the size of the grid’s step with the same keys during extrusion, you must be able to do what you want

(and ther’re a lot of other ways to do a revolution in Amapi)
