摘要
尽管AutoCAD为用户提供了标注形位公差的命令,但用该项命令所注出的代号,在框格尺寸、特征符号和附加符号等方面,均与我国现行的形位公差标准存在较大的差距。用AutoLISP语言开发的形位公差代号标注系统,不但可以快速注出符合标准规定的各种代号,而且利用系统设置的基准代号标注功能和循环运行模式,可以一次性完成图中所有基准和公差代号的标注。
Although AutoCAD provides users with a marked geometric tolerance of the order, but note that the order of the code, in the box size, the characteristics of symbols and additional symbols and so on, with our existing geometric tolerance standard there is a big gap. Code-named the function of the benchmark inconvenienced. Auto LISP language used to develop the geometric tolerance code tagging system, not only can quickly note that in line with the standards for a variety of code, and system settings to use the benchmark code tagging feature and recycling operation mode, you can complete a one-time map of all the benchmarks and tolerance code annotation.
