THE RESEARCH AND DEVELOPMENT OF POST-PROCESSING SYSTEM FOR CAD OF HIGH-RISING STEEL BUILDING BASED ON 3D SOLID MODEL

The research and development of post-processing system is the bottle neck of the CAD of steel structures. In this paper, the post-processing system for high-rising steel building based on 3D solid model is introduced. In this system, the complex spatial relationship between bars and detailed constitution of joints of steel structure is shown accurately in 3D solid model. Based on the 3D solid model, the drawing is created automatically in this system by using the geometrical and structural information of the solid model, namely the blue-print drawings, the designing drawings, and the manufacture drawings. Presently, this system has used in projects successfully.
