Abstract: Because of the enormous work in reverse engineering of automotive parts and components and the limitation of CATIA V5, it is hard to establish parametric models. Aiming at this problem, the combined use of Geomagic Studio and CATIA V5 to realize automated surface reconstruction was studied to rapidly achieve highaccuracy parametric models in reverse engineering of automotive parts and components. A case study of reverse design of a light engine cylinder head cover was described to reveal the general process of parametric design, which includes parts laser scanning with EXAScan Handed Laser Scan, preprocessing the cloud points and surface fitting in Geomagic Studio, and structural design and surface reconstruction in CATIA V5. The results indicate that this method applies well to the parametric modeling in reverse engineering of automotive parts and components, and provides much convenience for the development of new products.
