| 22 | class SurfPointEvolRadInv from BRepBlend |
| 23 | |
| 24 | inherits SurfPointFuncInv from Blend |
| 25 | |
| 26 | ---Purpose: This function is used to find a solution on a done |
| 27 | -- point of the curve when using SurfRstConsRad or |
| 28 | -- CSConstRad... |
| 29 | -- The vector <X> used in Value, Values and Derivatives |
| 30 | -- methods has to be the vector of the parametric |
| 31 | -- coordinates w, U, V where w is the parameter on the |
| 32 | -- guide line, U,V are the parametric coordinates of a |
| 33 | -- point on the partner surface. |
