There is no intersection point between Cu1 -- and OnLine. The distance between the line and the -- circle is greater than Radius. -- With Tolerance we will give a solution if the -- distance between Cu1 and OnLine is lower than or -- equal Tolerance. -- inherits Entity from Standard uses Lin2d from gp, Circ2d from gp, Pnt2d from gp, Array1OfCirc2d from TColgp, Array1OfPnt2d from TColgp, QualifiedCirc from GccEnt, QualifiedLin from GccEnt, Array1OfReal from TColStd, Array1OfInteger from TColStd, Position from GccEnt, Array1OfPosition from GccEnt raises NegativeValue from Standard, OutOfRange from Standard, BadQualifier from GccEnt, NotDone from StdFail is -- On a line .............................................................
