Parametric design is a crucial factor to consider in the BIM modeling application stage,as it can greatly enhance the speed of model generation and modification,leading to improved work quality and modeling efficiency.BIM parametric design of special-shaped steel structure roof is a prime example of its application,particularly in the challenge of modeling complex architectural shapes.To address this,this paper outlines a rapid modeling method for special steel structure roofs based on Grasshopper visual programming environment,using a stadium as a case study.The program combines Grasshopper visualization program and the intemode line segments for component position positioning and stretching path generation,allowing for quick model generation,efficient component size adjustment,and reduced modeling time.This method is highly practical in the protocol design stage and successfully demonstrates the feasibility of parametric design in actual projects.
