For the revolution, polar array feature, Spin Face, Torus Solid tools, it is possible to set the profile and other data but never the axis. This is a problem when creating variations, or when the rotation axis is modified by changing parameters. In this case the constraints on the profile are good, but not on the rotation axis. It is often possible with these tools to choose the rotation axis relative to the screen, to the drawing, to two points. It would be necessary to add the possibility of choosing the rotation axis on the drawing. For example a constrained line. The rotation axis will then be constrained to this line.
