摘　　要：传统的基于AutoCAD的地形图成图软件一般是通过常用的AutoCAD内部实体来表现地形图要素的,这种绘制方式存在明显的缺陷,即在表现相对复杂的地物时,地物过于零散,增加了用户编辑数据的难度,而且在数据组织上存在很大的冗余。ObjectARX软件开发工具中的自定义实体技术为我们解决这一问题提供了技术保障,本文简要阐述了定制AutoCAD自定义实体的基本过程。In general,the traditional AutoCAD-based topographic mapping software performance topographic maps elements by AutoCAD＇s basic entities,there are obvious shortcomings in this drawing means,that is when the performance of relatively complex features,the features are too fragmented to increase the difficulty of the user edit the data,And there are great data redundancy in data organization.The ObjectARX custom entity technology provide technical support for us to solve this problem,this paper describes a basic process of the AutoCAD custom entity.
