21 | ---Purpose: Function of reframing between a point and a surface. |
22 | -- This function is used to find a solution on a done |

23 | -- point of the curve when using SurfRstConsRad or |
24 | -- CSConstRad... |
25 | -- The vector <X> used in Value, Values and Derivatives |
26 | -- methods has to be the vector of the parametric |
27 | -- coordinates w, U, V where w is the parameter on the |
28 | -- guide line, U,V are the parametric coordinates of a |
29 | -- point on the partner surface. |
