从静态草图到参数化绘图程序自动转换

结合参数化设计和机械工程的实际,提出并深入研究了从静态草图到参数化绘图程序的自动转换问题。在建立图形转换模型的基础上,用AutoLISP编制了图形信息提取程序,用C 编制了转换程序。该转换程序能输出参数化的AutoLISP绘图程序,实现了从静态草图到参数化绘图程序的自动转换。实验结果表明:解决思路是可行的,在机械工程设计中有较大的使用价值。

Automatic Transformation from a Static Draft Drawing to a Parametric Drawing Program

Parametric design combined with mechanical engineering practice, the issue that transforms a draft drawing into a parametric drawing program is put forward and researched deeply. Based on a model, a AutoLISP drawing message extracted program and a C transformation program are developed. The transformation program can be used to generate AutoLISP parametric drawing program so as to achieve the transformation from a static draft drawing to a parametric drawing program. A practical example shows that the idea that solves the issue is available. The transforming program will be of great value in mechanical engineering design.
