Transformation Technique of Structural Models Based on Industry Foundation Classes Standard

Abstract:

Industry foundation classes (IFC) standard for data sharing and exchanging of building information modeling is introduced. The constitutions and the features of IFC files for architectural models and structural models are analyzed and compared. The transformation method of structural models based on IFC standard is investigated. The generation software of IFC files for structural models is developed with the ObjectARX technology on the AutoCAD graphics platform. A case study is implemented to illustrate the method of structural model transformation which shows that the software can extract the complete IFC information of structural models and it can realize structural model transformation from IFC standard to specific structure analysis software.
