class Cylinder from gp inherits Storable
--- Purpose :
-- Describes an infinite cylindrical surface.
-- A cylinder is defined by its radius and positioned in space
-- with a coordinate system (a gp_Ax3 object), the "main
-- Axis" of which is the axis of the cylinder. This coordinate
-- system is the "local coordinate system" of the cylinder.
-- Note: when a gp_Cylinder cylinder is converted into a
-- Geom_CylindricalSurface cylinder, some implicit
-- properties of its local coordinate system are used explicitly:
-- - its origin, "X Direction", "Y Direction" and "main
-- Direction" are used directly to define the parametric
-- directions on the cylinder and the origin of the parameters,
-- - its implicit orientation (right-handed or left-handed)
-- gives an orientation (direct or indirect) to the
-- Geom_CylindricalSurface cylinder.
-- See Also
-- gce_MakeCylinder which provides functions for more
-- complex cylinder constructions
-- Geom_CylindricalSurface which provides additional
-- functions for constructing cylinders and works, in
-- particular, with the parametric equations of cylinders gp_Ax3
