采用CAA对CATIA进行二次开发,建立了钣金零件的检验规划系统.通过钣金零件的检验规划系统得到特征的检验方法,并将所有特征对应的检验方法通过智能三维标注技术,标注到三维模型上.智能三维标注,即通过人机智能交互的方式,将所有的检验信息全部表示在三维图上,简单,直观,明了. The secondary development of CATIA was carried out by CAA, and the inspection and planning system of sheet metal parts was established.The testing method of the features was obtained by the inspection and planning system of sheet metal parts, and the testing methods corresponding to all the features were marked by 3D tagging technology to 3D On the model, intelligent 3D annotation, that is, through the way of human-computer interaction, displays all the test information on the 3D map, which is simple, intuitive and clear.
