AutoCAD线型二次开发在工程制图中的应用

摘要

The AutoCAD software system provides not only the standard linetype file, but also the interface for secondary development. Users can customize their own linetype files to meet the different needs. This paper introduces the basic methods of developing new linetype and shape file, and the linear definition methods in engineering drawing, such as dike, railway, the Great Wall and other commonly used linear symbols.%AutoCAD软件系统中提供了标准线型文件，同时也为用户的二次开发留出了接口，即用户可以定制自己的线型文件以满足不同的需要。文章简要介绍了开发线型文件和形文件的基本方法，并介绍了工程制图中堤防线、铁路线、长城符号等几种常用线型的定义方法。
