Aiming at the scanning point cloud data in reverse engineering, when extracting features of contour curve and generated surface, larger workload and easy problems, a kind of forward and reverse combination of surface reconstruction method was put forward based on feature data extraction and computer graphics aided three -dimensional interactive application (CATIA) secondary development. Firstly, in Geomagic Studio software to complete the scan data preprocessing of point cloud data, aiming at the characteristics of the different product model, different cross section lines and contour lines were extracted. Secondly, the features of model were analyzed, for a simple feature model by rotation, stretching and Joan command, the new model was regenerated. Finally, for complex surface modeling, to extract the feature point cloud data and to export for ASC format files, by means of CATIA secondary development, to read in the presence of a large number of data point coordinates in the EXCEL, the three dimensional (3D) models were generated quickly. Results indicate that: in Geomagic Studio with CATIA software as the tool, the characteristic curve extraction and feature point data read are completed, the modeling method of forward and reverse in combination was realized based on cross section and surface characteristics, which provides a new way for product modeling innovation design and rapid modeling.
