Research on Family of Object Model in Semantic Feature Modeling
语义特征造型中对象族模型研究

A new family of object model, i. e. declarative family of object model, was imposed in this paper. The model was defined, geometric and topological structure of this model was presented, semantic of feature was specified by constraints, constraint graph was used to represent features in the model, grammar specification of model was provided.Validation of the model was verified in a instance, and insufficient of traditional procedural-based modeling was overcome, design efficiency of CAl)modeling was developed, and design cost was reduced.
