  //! The cone is constructed about the "Z Axis" of either:
  //! -   the global coordinate system, or
  //! -   the local coordinate system Axes.
  //! It is limited in these coordinate systems as follows:
  //! -   in the v parametric direction (the Z coordinate), by
  //! the two parameter values 0 and H,
  //! -   and in the u parametric direction (defined by the
  //! angle of rotation around the Z axis), in the case of a
  //! portion of a cone, by the two parameter values 0 and
  //! angle. Angle is given in radians.
  //! The resulting shape is composed of:
  //! -   a lateral conical face
  //! -   two planar faces in the planes z = 0 and z = H,
  //! or only one planar face in one of these two planes if a
  //! radius value is null (in the case of a complete cone,
  //! these faces are circles), and
  //! -   and in the case of a portion of a cone, two planar
  //! faces to close the shape. (either two parallelograms or
  //! two triangles, in the planes u = 0 and u = angle).
  //! Exceptions
  //! Standard_DomainError if:
  //! -   H is less than or equal to Precision::Confusion(), or
  //! -   the half-angle at the apex of the cone, defined by
  //! R1, R2 and H, is less than Precision::Confusion()/H, or greater than
  //! (Pi/2)-Precision::Confusion()/H.f
