Repairing of panel CAD geometric model is an important pre-processing step of the finite element analysis, and widely used in the computer-aided geometric design field. This paper focused on the surface healing method of panel CAD model, which was proposed and analyzed by NURBS technology. Firstly, matching-curves border was determined fast through the pipeline method, the surfaces were stitched by the matching-curves method with characteristics. On the basis of the algorithm, a surface stitching program module was developed. The validity of algorithm was verified by healing automobile front fender parts.
