一个基于对话框的参数化表面粗糙度标注命令

A Parameterd Surface Roughness Marking Command Based on DCL Dialogue Box

用基于Visuallisp的AutoLisp语言和DCL对话框控制语言为AutoCAD建立一个在工程图上标注常用表面粗糙度符号的参数化绘图命令,Lisp程序可对所选择的控件产生一个回调函数,控制不同类型粗糙度符号的标注。

With AutoLisp and DCL(Dialogue Control Languige)we create a parameterized roughness drawing command for AutoCAD,so as to draw the roughness characters in engineering graphs correctly on the bases of national standard or GB.In the program the controlling unit chosen in the dialogue box should introduce a reacting function to draw the very type roughness note needed.
