Abstract: Due to the complex and diverse forms of joints, it is easy to cause difficulties in modeling and insufficient depth of joint design in the process of deepening steel structure joints by Revit software. Therefore, according to the requirements of the design code for beam-column joints of steel structures and combined with design and construction experience, a parametric family member model of beam-column joints, beam-beam joints, and column foot joints of steel structures based on the Revit family is established. The Revit application programming interface and C # code are used to identify the location of the target node in the model. The established steel structure node family model is selected and loaded into the actual project model to realize the automatic generation of a parametric steel structure node model. This method can quickly generate the steel structure node model, solve the problem of time cost in deepening the design of nodes, and greatly improve the work efficiency of designers.
