AutoCAD中表面粗糙度的标注

The quick mark of the surface roughness in AutoCAD

在AutoCAD软件中,没有表面粗糙度标注的命令。本文针对该软件在这方面的不足,通过制作、插入图块及编写AutoLISP程序,添加绘图命令,实现机件图样中表面粗糙度快速标注。

In AutoCAD,there are no such instructions as label for surface roughness.In order to solve the shortcomings of the software,this article deals with the problem by making and inserting blocks and programming AutoLISP,and adding drawing instructions for the purpose of realizing the quick mark of surface roughness.
