//! This class defines the infinite cylindrical surface. <br>

//! <br>
//! The "ZAxis" is the symmetry axis of the CylindricalSurface, <br>
//! it gives the direction of increasing parametric value V. <br>
//! <br>
//! The parametrization range is : <br>
//! U [0, 2*PI], V ]- infinite, + infinite[ <br>
//! <br>
//! The "XAxis" and the "YAxis" define the placement plane of the <br>
//! surface (Z = 0, and parametric value V = 0) perpendicular to <br>
//! the symmetry axis. The "XAxis" defines the origin of the <br>
//! parameter U = 0. The trigonometric sense gives the positive <br>
//! orientation for the parameter U. <br>

//! When you create a CylindricalSurface the U and V directions of <br>
