在机械 CAD/ CAM中 ,零件的相同结构的参数化是提高设计速度的重要标志之一。本研究针对Auto CAD平台上的三维实体功能以及 PDB管理功能的 DCL 技术 ,提出了利用标准结构的主要特征参数实现原型图的参数化方法。在 DCL 界面利用标准结构的三维实体模型实现图形库的可视化 ,原型图的参数化引入了特征参数。原型图的参数化与 DCL 界面用 Auto L ISP语言编写 ,虽然图的三维图样在目前情况还不符人们的习惯 ,但三维将最终替代二维图样。此方法操作简单 ,易于实现
In mechanical CAD / CAM, the parametrization of the same structure of parts is one of the important symbols to improve the design speed. In this study, aiming at the three-dimensional entity function of Auto CAD platform and the DCL technology of PDB management function, a parameterization method of prototype graph was proposed by using the main characteristic parameters of standard structure. In the DCL interface, a three-dimensional solid model of standard structure is used to visualize the graphics library. The parameterization of the prototype maps introduces the characteristic parameters. Prototype parameterization and DCL interface with Auto L ISP language, although the three-dimensional map of the map in the current situation is not consistent with the people’s habits, but the three-dimensional will eventually replace the two-dimensional pattern. This method is simple and easy to implement
