该程序经编译，生成AutoCAD的运行扩展程序，即扩展名为arx的文件，基于AutoCAD二次开发的盛行，很多的工程人员或者工程师要开发适合自己公司的产品，目前最最常用的工具就是Autodesk公司提供的ObjectArx。该程序就是用ARX开发的，里面有创建实体类（CreateEnt类）含有对象Line（直线）、circle（圆）、Pline（多段线）的构造函数的封装等等，以及对其相应属性进行修改的类（Modify），对初学ARX编程的人员特别有益！-The program by the compiler to generate the operation of AutoCAD extension, that extension arx file, based on the prevalence of AutoCAD second development, many engineers, or engineers to develop products suited to their company is currently far the most commonly used tool is the Autodesk provided ObjectArx. The program is developed with the ARX, which have to create entity classes (CreateEnt class) that contains an object Line (straight line), circle (round), Pline (multi-segment line) constructor packaging, etc., as well as to modify their corresponding attribute Class (Modify), for beginners ARX programming personnel particularly useful!
