CAD标准工作方法的研究

Investigations on the Standardization Method of CAD Application

为规范 CAD/ CAM系统的应用 ,本文从信息集成的角度出发 ,提出了 CAD标准工作方法 ,从主模型、文件命名、属性输入和重用、深度备份、参考集和图层等方面研究了 CAD数据的标准生成方法 ,并在 U G上开发了 CAD数据标准的生成和检查软件。该软件在企业的应用实施工作表明 ,采用 CAD标准工作方法和使用 CAD数据生成标准化软件 ,可以很好地规范 CAD数据的生成 ,既保证了设计各阶段数据的全相关、共享 ,也保证了主模型的安全 ,方便设计人员间 CAD数据的交换 ,提高 CAD数据共享程度和 CAD软件使用水平。

For better regulation of CAD application, a principle for standardization of CAD application is proposed from the view of information integration. It involves master model, file naming, attributes input and attributes reuse, depth backup, reference set, layer and so on. A software system has been implemented under UG for the standardization of CAD application and its verification. It was proven by industrial practices that the standardization of CAD application and its software can bring a better regulated CAD application so that the data collaboration, CAD model share and its data exchange, and a safe master model can be achieved. and then a higher level of CAD application can be expected.
