【摘要】 特征建模既包含几何信息 ,又包含部分非几何信息 ,便于设计及制造的集成。但基于特征的设计不支持设计早期的非几何决策过程。文章提出在基于 WINDOWS的开发环境下 (如 VC)进行模具设计早期工作 ,在 PRO/ E环境下进行产品详细结构设计 ,二者的结合采用 WINDOWS的消息驱动。更多还原

【Abstract】 Feature based modeling contains not only geometric information but also some non geometric information for easy CAD/CAM integration, but it does not support early non geometric design. This paper describes a practical method that can be used in mould design. Early design is developed based on general environment,for example,VC, and late detailed 3 D geometric design is under PRO/E. The interface is based on the message driven technique under WINDOWS programming.更多还原
