Detailed Description

Bounds for a cylindrical Surface.

These bounds may be used for a CylinderSurface In case of bounds for a StraightLineSurface the radius determines the radius within a localPosition is regarded as inside bounds.

CylinderBounds also enhance the possibility of a cylinder segment with an opening angle $2\cdot\phi_{half}$ around an average $\phi$ angle $\phi_{ave}$ .

CylinderBounds also supports beveled sides defined by an angle. Different angles can be defined on both sides of the cylinder. A positive angle is defined as "extruding" from the defined Zlength, while a negative angle is "intruding" on the Zlength.
