摘　　要：：This paper points out the limitations of both parametric and geometric model methodscommonly applied to generate operational sketches in CAPP. The ideas of multi-level graphic library areintroduced and a new generative method based on this library which combines parametric method withgeometric model method is presented. The principles and characteristics of the construction of the library aredescribed in detail and the feature data structure corresponding with the library is also presented.：This paper points out the limitations of both parametric and geometric model methodscommonly applied to generate operational sketches in CAPP.
