摘　　要：在机械制图中,零件图上的表面粗糙度标注是必不可少的。AutoCAD被广泛应用于机械制图的图形绘制,但是AutoCAD没有专门标注表面粗糙度的功能,论文针对该软件在表面粗糙度标注方面的不足,充分利用属性块的特性,把表面粗糙度Ra的数值定义为2个可变属性块,利用插入块的方法标注表面粗糙度。这样就能够大大提高绘制零件图的效率,并且符合国家标准规定。In machinery cartography, surface roughness degree must be labeled in the part diagrams. AutoCAD is widely used in machinery diagrams charting, but there isn＇t the function of the surface roughness degree labeling in it. Aiming at the shortage of the software, the present article makes full use of the characteristic of attribute modules and defines the numerical value of the surface roughness degree Ra as two changeable attribute modules, and uses plug block to label the surface roughness degree, which can improve the efficiency of part diagrams charting a lot, and accords to the national standards, too.
