摘要
回顾了现有CAD系统所采用的主流、成熟技术 ,包括特征造型技术 ,基于历史的造型、参数化设计以及组件技术 从工业界的角度分析了当前CAD技术的若干研究主题 ,包括CAD与互联网、曲面造型、数据交换、从二维到三维、概念设计与早期设计等 并展望了未来的CAD系统 ,包括未来的计算环境、未来的机械CAD。
This paper reviews the mainstream technologies used in current CAD systems, including feature-based modeling, history-based modeling, parametric technology, and component technology. Research issues in current CAD systems, such as CAD and Internet, advanced surface modeling, data exchange, 2D vs. 3D CAD, and support for conceptual design are discussed. The paper concludes with some predictions on future CAD systems, with focuses on computing environments, mechanical CAD, data exchange and sharing, and part modeling technologies.
