飞机钣金零件二维展开视图自动标注弯边角度系统

Automatic Angular Dimension System of Flat Pattern View for Aircraft Sheet Metal Component

如何快速生成钣金件二维展开标注视图是飞机制造过程中的一个重要问题。介绍了飞机钣金零件二维展开视图自动标注弯边角度系统的组成及各功能模块的实现方法,应用交互模式的CATIA二次开发技术及CAA二次开发包,完成了VC++环境下的软件系统设计,并以实例说明了零件的展开标注过程。

Quick generation of sheet metal components＇ flat pattern dimensional view is one of the most important issues in the process of aircraft manufacture. The structure and realization method of automation angular dimension system is introduced in this paper. Using of interactive mode CATIA second development technology and CAA second setups, the VC＋＋ environment of software system design is finished, and explained with an example.
