Taking the table tennis hall project of Hangzhou Asian Games as an example, this paper analyzes the application of BIM parametric technology in non-linear building. According to the characteristics of the project, starting from two aspects of building volume and structural system, all the space control points of the original scheme of table tennis hall are given function relationship, and the control points are optimized and adjusted in three-dimensional space by parameterization to realize the nonlogical special-shaped modeling effect of building fa?ade. Under the premise of ensuring the design concept of table tennis hall, coordinate the implementation of professional construction drawing design and construction. This paper analyzes the application of BIM parametric technology in the project from the aspects of facade curtain wall system, special-shaped roof drainage system, roof steel structure grid system, and curtain wall steel structure grid system to provide reference and experience for the positive design and parametric design of similar non-linear buildings.
