| 摘 要： | 地理信息系统中存在许多等高线文件,如何利用等高线文件进行建模来节省人力物力已经变得很重要。本文利用C#语言调用ObjectARX托管封装类进行编程,建立AutoCAD建模命令,在AutoCAD环境下调用建模命令实现自动建模,提高数字化成图的效率。

| Abstract: | There are many contour line documents in geographic information system,so we need to know how to save manpower and resources while modeling using these documents.The paper introduces how to use ObjectARX collocation and capsulation classes within C# while programming to build AutoCAD modeling commands,and then uses these commands to model automatically to improve the ratio of digital maps. |
