Abstract: For most free forms, we usually start from the logical structure of mathematics. However, it is difficult to control the building form from the overall perspective, and as a result, we often have a deviation from the overall control of the design trend. In order to solve this design problem, according to the practical experience of TIENS University Sports Center project, we present a set of digital construction and logic optimization experience. We hope to bring some useful inspiration to the design of such projects.
