In rotation about an axis, each point P of the set S of all points of unextended space is carried into a point P1 of S by rotating P about a fixed line in space through a given angle.

The fixed line is called the axis of rotation.

For a detailed description of the object created Q, use the routine detail (i.e., detail(Q))

The command with(geom3d,rotation) allows the use of the abbreviated form of this command.
