| 摘 要： | 1 Introduction Reverse engineering (RE) is ani mportant method in constructing a CAD model froman existing physicalpart during part or product design. Whenthe digitized points are available ,the CAD model could be constructedby NURBS curves or surfaces fitting, whichis a commonly available and widely used method.Many efforts have been made in constructing CAD models by fitting NURBS curves and surfaces topoints[1 ,2]. As constructing NURBS surface is usually not a stand-alone projec…

| Abstract: | The method of reconstructing NURBS surface with features is proposed in this paper. Features including boundary curves and feature points are recognized from the scanned data. An initial surface is constructed with boundary curves. The desired NURBS is determined by modifying the initial surface to pass through feature points. Lagrange multiplier is used to find the solution. The error analysis is then done. Examples are given to verify the algorithm at last. The method can keep some features fixed and be widely used in CAD modeling. |
