基于新国标和CAD的表面粗糙度快速标注

Fast Mark of Surface Roughness Based on New National Standard and CAD

基于新的表面粗糙度国家标准,以VB.NET为编程语言,对Auto CAD进行二次开发,实现CAD环境下表面粗糙度的快速标注,提高设计人员机械表面精度设计的效率。

In this paper, based on new national standard, one apply the VB.NET to develop AutoCAD and mark the surface roughness quickly, as a result, to improve the efficiency of design.
