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 更多...
