Abstract:

As one of the world’s most widely used drawing platform in engineering and research field currently，AutoCAD software has the significant value in mining field.In order to improve the function and application value of 3D Modeling Visualized Integrated System of Goaf which was developed independently，CAD data interface of the integrated system was developed on the basis of researching the data storage structure of dxf file used universally by CAD and summarizing the data storage rule of different graphic elements.Through the interface，the data in dxf file about goaf’s point cloud model，profile and triangular mesh entity model could be read by integrated system.At the same time，the dxf files about goaf’s point cloud model，profile，and triangular mesh entity model could be generated automatically.CAD Data Interface effective development methods was presented，data storage structures of different graphic dxf file was parsed，store law of different data elements in the dxf file was summarized.The practical application showed that data sharing between the integrated system and AutoCAD was well realized through this interface，so great conveniences could be brought in the work surrounding goaf，like relevant mining design.And this achievement can provide useful reference to research on the CAD interface.

Key words: goaf , 3D modeling, visualized integrated system, CAD data interface, development
