尺寸公差标注系统设计

摘要

It is essential to mark common difference measurement in a machine drawing. In order to make the measurement marked in CAD software accord with the machine drawing standard in our country, using AutoCAD R12 as operating panel, in DOS setting, author uses AutoCAD R12 developing system that is, ADS language.to research and develop the system for marking measurement.%尺寸公差标注是绘制机械图的一项重要内容。为了使机械CAD软件中的尺寸标注符合我国机械制图标准，作者以AutoCAD R12为操作平台，在DOS环境下，利用AutoCADR12的高级用户开发系统，即ADS语言及对话框控制语言(DCL),研究并开发了尺寸标注系统。
