摘要：
The function modeller presented in this paper was designed to extract product features for automatic process selection in an independent application. This modeller works on principles of Boundary Representation (B-Rep), specifically Euler formula and Attributed Adjacency Graphs and Constructive/De-Constructive Solid Geometry(CSG) modelling. These models are reviewed and presented as introductory material to this paper. The product CAD data that is used within these principles is obtained from a neutral STEP file format, ensuring its compatibility amongst existing CAD programs. A recursive checking method, utilising volume decomposition of a CSG model, is employed to ensure that a valid product model is developed.
