Auto　CAD中零件表面粗糙度标注功能的开发

The Development of Surface Roughness Auto-marking Function of Part Drawing in Auto CAD

论述了以计算机绘图软件AutoCAD为图形支持软件，实现零件图表面粗糙度自动标注的程序设计方法，用这种方法使零件图表面粗糙度的自动标注成为可能。

In this paper, the program design procedure of surface roughness Automarking of part drawing is introduced in detail. It is supported by software Auto CAD. The program designed by this procedure makes it possible to mark surface roughness automatically.
