ARX开发环境下矩形网自动绘制等值线的实现

Realization of drawing equivalent line automatically in rectangle net under ARX develop environment

等值线的自动绘制是针对地质工作的AutoCAD二次开发的一项重要工作,ARX是AutoCAD的二次开发工具的一种,文中对ARX动态链接库的结构、AutoCAD图形数据库结构、AutoCAD中非图形特征的存取等进行简单的介绍,并描述在ARX开发环境下实现矩形网自动绘制等值线的一般过程,提供一种利用ARX环境开发等值线自动绘制的方法。

The automatic drawing of equivalent line is one of the importance work to the secondary development of AutoCAD in geology work,ARX is a tool of the secondary development of AutoCAD, this article will give a short introduce to the structure of ARX Dynamic-Link Liabrary,the structure of AutoCAD AcDbDatabase,the save and load of the non＇figure characteristic in AutoCAD, and describe how to draw equivalent line in rectangle net automatically under the develop environment of ARX. and provide a method of how to develop the automatic drawing of equivalent line in ARX environment.
