  //! The cylinder is constructed about the "Z Axis" of either:
  //! -   the global coordinate system, or
  //! -   the local coordinate system Axes.
  //! It is limited in this coordinate system as follows:
  //! -   in the v parametric direction (the Z axis), by the two
  //! parameter values 0 and H,
  //! -   and in the u parametric direction (the rotation angle
  //! around the Z Axis), in the case of a portion of a
  //! cylinder, by the two parameter values 0 and Angle.
  //! Angle is given in radians.
  //! The resulting shape is composed of:
  //! -   a lateral cylindrical face,
  //! -   two planar faces in the planes z = 0 and z = H
  //! (in the case of a complete cylinder, these faces are circles), and
  //! -   in case of a portion of a cylinder, two additional
  //! planar faces to close the shape.(two rectangles in the
  //! planes u = 0 and u = Angle).
