摘要
提出了面向模具零件工程图的孔特征识别与分组统计方法,采用特征识别实现了尺寸功能语义的再现,基于此进一步实现了孔系的自动分组统计.该方法在AutoCAD软件中利用VisualLISP得到实现.测试结果表明所提出的算法可以很好地解决尺寸完整性问题,完善了模具零件尺寸自动标注功能.
An approach to the feature identification and counting of the hole features for the Die ＆ Mould engineering drawing was proposed to address automatic datum dimensioning. The combination notes of the functional semantic and counting results of the hole features can be given at the same time in the drawing, based on the feature identification. The proposed approach has been designed and implemented by utilizing the programming language, VisualLISP provided by AutoCAD. The practical datum dimensioning cases were given to illustrate the important features of the approach. The results indicate that the proposed approach accomplish the function of automatic datum dimensioning.
