摘要
介绍AutoCAD图形数据库的组成,并给出一种应用ObjectARX技术来提取AutoCAD图形数据的程序实现方法。应用本方法提取地形等高线、地质界线等数据用于建立三维地表模型取得很好的效果,为三维地表建模的数据获取提出一条快速的途径。
This paper introduces the constitutes of AutoCAD graphics database,and gives an implement method of extracting data from AutoCAD graphics by using ObjectARX.It has achieved good results to apply the method to extracting the data of topographic contours and geological borderlines used in three-dimensional surficial modeling.It proposes a fast way for the data extraction of three-dimensional surficial modeling.
