【摘要】 应用AutoCAD内嵌的AutoLISP语言和DCL分别编写绘图程序和人机交流的对话框,探讨了实现发动机零件图参数化绘制方法。以发动机平切口连杆为例,编写了图纸参数化绘制程序,并详细阐述了其实现过程。实际应用证明,零件图参数化绘制方法可以大大减少工程设计人员的重复劳动,并可用于开发其它结构形状已定型零件的参数化绘图程序。更多还原

【Abstract】 The method of parametrization drawing of engine components is introduced which is based on the application of the AutoLISP in AutoCAD and DCL to the compiling of the program. The parametrization drawing program of the connecting rod of the engine is compiled, and its realizing process is presented in detail.It has been proved in practical application that the repeated work of designers can be reduced greatly and the parametrization drawing program of other components having certain structure can be developed by using the method of parametrization drawing.更多还原
