This paper analyzes the reasons that affect the efficiency of structural design, and proposes a BIM forward designing method based on Revit. The BIM model standard data of structural design is studied in depth, and conclusion is made that the standard data satisfies the design habits for structural construction drawings throughout the country.Currently, the key technologies for BIM forward designing method include Revit rapid modeling, BIM model calculation and BIM plotting. This paper solves the three key technologies through investigation and implements them through software development. According to the method proposed in this paper, the design efficiency and quality can be significantly improved by using Revit instead of AutoCAD for structural design, and the problems of BIM application in the whole process of structure design can be solved. The research of this paper will promote the development of BIM application in the whole industry.
