Methodology of 3D Geometric Modeling and Model Conversion of IFC-based BIM
Department of Civil Engineering, Tsinghua University, Beijing 100084, China |
Contrast to the traditional paper-based information representation methodology which uses 2D graphic primitive elements such as point, line, face etc., the application of 3D digital technologies in A/E/C(Architec-ture/Engineering/Construction) domain significantly improves the efficiency of construction information communications and has become a key technical support of BIM (Building Information Modeling). The various types of 3D geometric representations can be classified into solid model, surface model and framework model, each of which can be applicable in specified application areas and scope. To meet the requirements of BIM applications in different phases of A/E/C, a methodology of 3D solid modeling and converting it into surface model of IFC-based BIM is proposed in this paper, which adopts AutoCAD graphic engine. Its feasibility is verified by some tests.
