Study on Statistical Method of Steel Bridge Parts Information Based on Three-Dimensional CAD
Parts information of steel bridge with tens of thousands of parts is difficult to be managed and be executed statistics. On the platform of three-dimensional CAD systems, steel bridge node is the study object in this paper, according to the assembly relationship of all parts in the three-dimensional assembly model, the parts list, quantity, geometrical information and weight of the parts of the steel bridge nodes are extracted from a three-dimensional model by the application interface provided by three-dimensional CAD systems. On the basis of geometrical information of the parts, the minimum boundary dimension of the parts is computed by use of the principle of computer graphics. The method can rapidly and accurately obtain parts information, and can provide basis for assembly process and processing technology.
