void  LoadInitSurface (const TopoDS_Face &Surf) 
Loads the initial surface Surf to begin the construction of the surface. This optional function is useful if the surface resulting from construction for the algorithm is likely to be complex. The support surface of the face under construction is computed by a deformation of Surf which satisfies the given constraints. The set of bounding edges defines the wire of the face. If no initial surface is given, the algorithm computes it automatically. If the set of edges is not connected (Free constraint), missing edges are automatically computed. Important: the initial surface must have orthogonal local coordinates, i.e. partial derivatives dS/du and dS/dv must be orthogonal at each point of surface. If this condition breaks, distortions of resulting surface are possible. More...
