基于CATIA的汽车三维GD&T自动标注的研究与实现

Research and implementation of 3D GD&T auto annotation of automobile based on CATIA

随着三维GD&T标注在汽车行业应用的日益普及,由于其专业性强且工作量巨大,令各大主机厂烦扰不堪。某公司通过VC++2008对CATIA进行二次开发,实现了三维GD&T的自动化标注。该工具大大提高了三维GD&T标注的正确性,在减少了人力资源的同时,还大大缩短了GD&T开发周期。文章阐述了三维GD&T自动化标注的实现策略和方法,对汽车行业MBD的发展起到了积极的推进作用。

With the increasing development of 3 D GD&T in automobile industry, major OEMs are bothered because of its strong professionalism and huge workload. Our company carried out the secondary development of CATIA through VC++ 2008, and realized the automatic annotation of 3 D GD&T. This tool greatly improves the accuracy of 3 D GD&T, while reducing human resources, it also greatly shortens the development cycle of GD&T. This paper describes the strategies and methods for the realization of 3 D GD&T automatic annotation, which plays a positive role in promoting the development of MBD in the automotive industry.
