摘要：

The paper describes the implementation of a geometric modelling system named PIGMOD with a parametric design capability based on non-manifold geometric modelling. The basic idea is that a set of modelling operations can be so defined that there are correspondences between the geometric constraints and the modelling operations. The geometric relations are represented internally in terms of the modelling operation sequence. The modelling operations are implemented as manipulations on a non-manifold geometric model. The methods for modifying the geometric model automatically and consistently in accordance with changed or added dimensions are implemented in a simple and unified way.
