【摘要】 在产品模型中引入编码和抽象的概念,在此基础上构建了设计空间模型。通过应用实例分析了设计师和CAD工具在设计空间中的工作模式和行为特点,总结了为提高设计师工作效率,设计师和CAD的最佳合作方式,从支持空间的角度讨论了各种类型的知识对设计过程的辅助方式。对CAD软件功能的研究方向进行了分析,给出了智能化CAD系统的层次化开发建议。更多还原

【Abstract】 Abstracting coding was introduced to product model,on which a conceptual Design Space was established based.Behaviors of designer and CAD in design space were analyzed with cases,the best way to improve designer’s efficiency is by assigning the roles of designer and CAD in design process.All kinds of knowledge in Supporting Space were analyzed about how to aid designers.At the end,the hierarchy system of intelligent CAD functions and its developing directions were analyzed.更多还原
