摘要
文章分析了AutoCAD的DXF文件格式,介绍了基于DXF文件提取所需数据的接口程序设计,并给出了一种从AutoCAD图形中提取数据的Delphi程序实现方法。应用此方法提取地形等高线、地质地貌特征和钻孔柱状图等数据用于建立三维地质模型取得了很好的效果,有效的解决了AutoCAD系统与三维地质建模及信息可视化系统的图形、数据的相互转换问题,为三维地质建模数据的获取提出了一条新的途径。
This paper analyzes the format of DXF file of AutoCAD, introduces the interface programming for the extraction of required data based on DXF file, and gives an implement method with Delphi for extracting the data from AutoCAD graphics. It has achieved good results to apply the method to extracting the data of topographic contours, geomorphic features and bore logs used in three-dimensional geological modeling. And it has effectively implemented the mutual conversion of the graphics and data between AutoCAD system and three-dimensional geological modeling and information visualization system. It has introduced a new way for the data acquisition of three-dimensional geological modeling.
