Abstract: The research and application of BIM method in 3D information model of architectural structure were mainly discussed, by which a method of BIM technology about building a 3D information model was provided based on the platforms of Geomagic Studio, Autodesk Revit Software. In this method, the advantage of BIM technology was obviously. Finally, through making a BIM information model of the structure buildings, the building adjacent structures were given to build parameterized library. The BIM model was exported to the file format which is called the IFC, other software in the method of BIM can use the IFC files to share the information model. This method confirm that the BIM technology in the 3D information modeling structure was feasible.
