Abstract. The grid system of traditional Chinese timber structure building is generally rectangular or in other regular geometric shapes. Due to construction errors, building deformation and other reasons, the actual grid system obtained by laser 3D scanning technology is usually not in regular shape. The purpose of HBIM is to favor regularity, and it is necessary to carry out regularized reconstruction on the grid system. By reconstruction of the grid using genetic algorithm in Grasshopper, feasible regularized HBIM models can be obtained.
