Revolve Tool The revolve tool uses a sketch and a reference for the Axis of Revolution.  By default, the system will use the first centerline created in the sketch.  If you have multiple centerlines, you can right-click and specify one as an Axis of Revolution. The revolve tool also allows to select an axis or edge as an Axis of Revolution, but it must lie in the sketching plane to be valid.
