The Axis element gives the nominal location of the start point and the nominal unit cylinder axis vector. The direction of the axis vector points into the cylinder. The cylinder does not extend from the start point in the direction opposite the axis vector.

The optional Sweep element gives the start direction and the swept angle for a partial cylinder. The swept angle is typically greater than 180 degrees for a feature of size. If the sweep is not specified the feature subtends a full 360 degrees. The StartVector of the Sweep must lie in a plane normal to the axis of the cylinder.
