机械CAD软件的二次开发

Again Developing the Autocad in Mechanical Engineering Designing

介绍基于ＡｕｔｏＣＡＤ开发机械ＣＡＤ软件的方法，包括数据管理、形位公差标注、标准件建库等问题，所开发的软件符合国家有关制图标准。

This paper describes the methods to develop mechanical engineering CADsoftware based on AutoCAD system, including data management,the form and posi-tion tolerance marking,the standard mechanical component library building,and soon. The software built with these methods is in keeping with the demands of drawing standardization.
