Abstract: To improve the efficiency of Boolean operations in semantic feature modeling system, a semantic representalion based method was proposed. It represents feature models with semantic representation, manages feature elements by cellular model,improves detect efficiency of features interaction and builds new the feature entity by splitting ntersectant cells and semantic faces. hhis method can not only build the Boolean entity rapidly and exactly, but also avoid crrors such as holes and losing geometry faces. Experiments on computer show that this new method is more adaptable and practicable.
Key words: CAD, Semantic representation, Boolean operation, Cellular model, Feature
