Auto CAD二次开发表面粗糙度标注命令

Auto CAD secondary development of indicating command of surface roughness

AutoCAD是工程界最著名的绘图软件之一,由于其功能强大,而被人们广泛的采用。但在绘制机械图样时却没有提供关于表面粗糙度的标准方法,表面粗糙度是衡量零件表面加工质量的重要参数,是零件图中必不可少的标注内容之一。因此实现快速、自动标注表面粗糙度的具有非常重要的意义。在AutoCAD2000/2002中利用VBA二次开发环境,实现表面粗糙度的命令标注。

Auto CAD is one of the most important drawing software. It is widely used due to its powerful functions, but it does not provide the method of surface roughness in mechanical drawings, which is the important parameter measuring parts surface quality, and one of the essential indicating contents in detail drawings, therefore, it is vital to realize immediate and automatic indicating surface roughness. This paper makes use of VBA secondary development environment to carry out indicating surface roughness in Auto CAD 2000/2002. 
