摘要
介绍三维模型生成二维工程图过程中,存在标注繁琐以及尺寸标注不全、标注混乱等问题,研究基于三维软件UG NX平台,建立了零件工艺信息数据库,通过特征识别方法提取模型特征信息,构造零件特征邻接属性图,运用UG二次开发技术,自动调用自定义工程图模版,实现了三维模型的自动标注,实例分析表明:研究开发的工程图自动标注系统极大地减少了图纸设计工作量,有效提高了设计效率。
In order to solve the problem that existing complicated and messed dimensioning and lack of dimensioning in the process of the 3D models generate to 2D engineering draw- ings, it developed an automatic dimensioning system for engineering drawing based on the UG NX platform. With establishing the parts processing information database, the model＇s feature information was extracted and the attributed adjacency graph was built via feature recognition with the technology of uG secondary development, automatically calling the custom engineering drawing template to accomplish the automatically dimensioning of 3D model. An example analysis showed that the system greatly reduced the workload of drawing design and improved the efficiency of drawing dimensioning.
