Applying reverse engineering technique to reconstruct the CAD models is an important part in the product development. By that we can get some experiences about the techniques of the product design and manufacturing. Lamps in auto industry are complicated geometric shape and the reconstruction of the CAD models for them is a difficult work, which requires experienced CAD skills. The purpose of this study is investigate the reverse engineering technique for the reconstruction of the CAD models for lamps, focusing on the issues of surface reconstruction. Two software, including RevCAD and UG, are applied for the investigation of the surface reconstruction technique in this study. The quality of the reconstructed surfaces are discussed also with several inspection tools available in the software. The availability and characteristic of all tools, including surface reconstruction and surface inspection, will be analyzed and discussed in detail.
