Detailed Description

This class implements the following algorithms used to create a CylindricalSurface from Geom.

The "ZAxis" is the symmetry axis of the CylindricalSurface, it gives the direction of increasing parametric value V.

The parametrization range is : U [0, 2*PI], V ]- infinite, + infinite[

The "XAxis" and the "YAxis" define the placement plane of the surface (Z = 0, and parametric value V = 0) perpendicular to the symmetry axis. The "XAxis" defines the origin of the parameter U = 0. The trigonometric sense gives the positive orientation for the parameter U.

)

A2 defines the local coordinate system of the cylindrical surface. The "ZDirection" of A2 defines the direction of the surface's axis of symmetry. At the creation the parametrization of the surface is defined such that the normal Vector (N = D1U ^ D1V) is oriented towards the "outside region" of the surface. Warnings : It is not forbidden to create a cylindrical surface with Radius = 0.0 Status is "NegativeRadius" if Radius < 0.0.
