Aiming at solving the problems of low efficiency and complicated operation of 3D modeling in the process of virtual product development of national culture, this paper discusses a synthesis approach of surface geometry model based on data-driven. Firstly, a shape-based matching algorithm is used to retrieve the corresponding components in the database. Secondly, a new model will be generated through segmenting and assembling these components. Finally, this approach is applied to construct 3D
