| Abstract: | 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. |
