//! - The Center element (circle, line).
//! - A real Tolerance.
//! Tolerance is only used in the limits cases.

//! centered on a line OnLine with a radius Radius and with
//! a tolerance Tolerance.
//! If we did not use Tolerance it is impossible to

//! and OnLine. The distance between the line and the

//! With Tolerance we will give a solution if the
