Abstract: In this paper, the flat method construction drawing of building structure and the object type and description mode of the structural members in the BIM model are analyzed. Based on the design features of the frame structure, it proposes a parametric design model of frame structure based on BIM technology. with the secondary development of AutoCAD and BIM software and with Excel as the data storage and additional input tool, it achieves the information extraction of Satwe calculation results in the two-dimensional graphics and structural members in the structure construction drawing, accomplishes the optimization design of frame structure reinforcement and automatic three-dimensional BIM modeling and interactive design, carries out the program implementation on CATIA, and applies it to the practical engineering.
