GccAna_Circ2dTanOnRad (const GccEnt_QualifiedCirc &Qualified1, const gp_Lin2d &OnLine, const Standard_Real Radius, const Standard_Real Tolerance)  
This methods implements the algorithms used to create 2d Circles tangent to a circle and centered on a 2d Line with a given radius. Tolerance is used to find solution in every limit cases. For example Tolerance is used in the case of EnclosedCirc when RadiusR1+dist is greater Tolerance (dist is the distance between the line and the location of the circ, R1 is the radius of the circ) because there is no solution. raises NegativeValue in case of NegativeRadius.
