21 ---Purpose: This function is used to find a solution on a done
22 -- point of the curve 1 when using RstRstConsRad or
24 -- The vector <X> used in Value, Values and Derivatives
25 -- methods has to be the vector of the parametric
26 -- coordinates w, U where w is the parameter on the
27 -- guide line, U are the parametric coordinates of a
28 -- point on the partner curve 2.
