Analysis and realization of UDF in design of the blade;

叶片设计中用户自定义特征的分析与实现

According to the User Defined Feature (UDF) in CAD system and engineering management of KBE, this paper builds a basic framework of intelligent parametric design for tube.

利用CAD系统的用户自定义特征与KBE的工程处理能力,构建了管道智能参数化设计的基本构架,通过建立专业知识库来实现对管道模型的知识驱动,并结合工程实际给出优化方案。

It elaborates the application of Pro/engineer in industry design,including Parallel engineering,UDF,building standard parts library and the skill of operating Pro/engineer.

结合开发实例,叙述了使用用户自定义特征(UDF)、建立标准零件库、曲面实体混合造型等一些使用Pro/engineer软件的技巧。

A modeling method of history-based user-defined feature is proposed and implemented in a3d parametric system named Intesolid,a self-developed CAD system copyrighted by CAD Center of Huazhong university of science and technology.

在华中科技大学CAD中心自主开发的三维CAD系统———Intesolid中,提出了一种基于历史的用户自定义特征的建模方法,实现了基于用户自定义特征的设计意图的重构,提高了设计效率,体现了设计构件重用的思想,并简化了特征库的管理。
