This paper presents the methodology for repairing NURBS based geometry of CAD models. A weighted least squares method is employed for refitting a NURBS surface with mismatched edges, the construction of surfaces from point clouds, or the reconstruction of surfaces to improve the quality of grids generated for physics based simulations.
