Detailed Description
This class implements the following algorithms used to create a CylindricalSurface from Geom.
- Create a CylindricalSurface parallel to another and passing through a point.
- Create a CylindricalSurface parallel to another at a distance <Dist>.
- Create a CylindricalSurface passing through 3 points.
- Create a CylindricalSurface by its axis and radius.
- Create a cylindricalSurface by its circular base. The local coordinate system of the CylindricalSurface is defined with an axis placement (see class ElementarySurface).
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.
