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