本小节通过一个简单的实例来讲述ARX程序的创建过程，介绍编制Object ARX程序的一些基本步骤和原则，并初步了解ARX程序与AutoCAD进行通讯的方式。如同学习其它计算机语言一样，我们首先来创建一个最简单的ARX程序—“Hello.ARX”，在AutoCAD 2002中加载并运行该程序，将会在命令行出现－“Hello, ObjectARX!”。-This section through a simple example to describe the creation of ARX program, introduced procedures for the preparation of Object ARX some basic steps and principles, and a preliminary understanding of ARX procedures and AutoCAD for the means of communication. As learning other computer languages, we first of all to create one of the most simple ARX procedures-　Hello.ARX , in AutoCAD 2002 to load and run the program, it will appear in the command line-　Hello, ObjectARX! .
