Paper Abstract

A feature-centered scheme is presented to represent the feature-based variational part model. Constraint reasoning approach combined with numerical approach is triggered to satisfy the constraints between features. Coassociations between boundary primitives in feature level and part level are maintained to implement a series of feature operations and to implement precision feature modeling for parametric part geometry model. GHCAD, a feature-based parametric modeling system based on these ideas, is developed.
