The mathematical principle for sweeping solids, the valid sweeping solid defining rules, the principle of validity check and the discretization procedure are discussed. The factors influencing the stability of Boolean operation are analyzed, and a robust set operating algorithm on sweeping solids is proposed, The generalized sweeping primitives and the robust set operating algorithm proposed have been used in a feature solid modelling tool system (FSMTS) developed at the author's university. A user-defined primitive base can be generated by FSMTS, in which the primitives are defined by a set of generating-line-elements and their sweeping method. Each primitive created by FSMTS can be accepted by a standard Boolean operating processor, and robust set operations can be carried out.

This paper summarises the difficulties met in representating the mechanical product feature information by single CSG model or B-ReP model. According to the special requirements of integrated CAD/CAM systems, an method of feature information repre sentation is proposed based on the CSG + B-ReP data structure. The main characteristics of the method are that face is used as an unit for the feature definition; and making use of the coordinative relationship of CSG aad Rep in the FSMTS ( Feature Solid Modelling Tool System), product information table (PIT), CSG, and B-ReP are linked up to form an adjacency list. As the result, the parametric product model can be set up by the CSG description; the geometry can be defined, and the feature information can be added interactively throngh the B-ReP model.
