| 摘要: |
| 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AutoCAD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AutoLISP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。 |

| Abstract: |
| The parametrization of the same structure ofmachine partis an importantsign foradvancing design speed in machanism CAD/CAM.This article elaborates the theory and method for realizing parametrization of the original design.In the DCL interface,graph data videotex has been realized by using standard three-dimension object model,stamp parameter has also been introduced.The parametrization of the archetypal drawing and the DCL interface are depicted with Auto LISP.Although the three-dimension draft have not accorded with folk custom,it would take the place of two-dimension drawings in the near future.This method is simple and easy to be fulfilled. |
