摘要
阐述了各种情况下准确标注表面粗糙度代号所需的关键角度ANG的确定方法,介绍了利用AutoLISP语言为AutoCAD增加表面粗糙度标注命令的程序实现过程和命令加载方法。通过运行此命令,能够在所选实体的指定位置自动生成符合国家标准规定的表面粗糙度代号。
This paper deals with the method of calculating the key angle ANG that is necessary to marking surface roughness accurately under different conditions. With AutoLISP, a program used to mark surface roughness accurately is given, that can be used as a new command of AntoCAD. In addition, put forward a method of loading this new command. By running this command, the roughness symbols that accord with the national standard can be automatically created in the appointed position.
