| 19 | inherits SurfPointFuncInv from Blend |
| 20 | |
| 21 | ---Purpose: This function is used to find a solution on a done |
| 22 | -- point of the curve when using SurfRstConsRad or |
| 23 | -- CSConstRad... |
| 24 | -- The vector <X> used in Value, Values and Derivatives |
| 25 | -- methods has to be the vector of the parametric |
| 26 | -- coordinates w, U, V where w is the parameter on the |
| 27 | -- guide line, U,V are the parametric coordinates of a |
| 28 | -- point on the partner surface. |
