基于CAD图纸的BIM模型轴网生成方法研究

Research on Axis Generation in BIM based on CAD Drawings

摘要: 本文通过对CAD图纸文件生成的DXF文件进行分析，识别图纸中的轴网与编号。同时，采用Revit二次开发技术，根据获取的CAD信息，在Revit模型中自动生成相应的轴网与轴网编号.减少了当前人工依据CAD图纸搭建BIM模型的工作量。

Abstract: This paper presents the recognition of the axis line and the numbers on axis by analyzing the data of DXF file exported from CAD drawing. After that, based on the CAD information, the program auto-generate the axis and number in BIM on the secondary development of Revit package. It reduces the time for building the BIM model from CAD drawings.
