With the rapid development of the digital design technology in the ship industry, the digital design technology based on the three-dimensional model is widely applied to the ship field. In a hull structure, in order to ensure the continuity of longitudinal sectional materials of a hull and meet the structural strength requirement, sectional material through holes are required to be designed. However, the through holes have complicated profile design due to the variety of intersecting forms (especially non-orthogonal) between the profiles and the plates. On one hand, in order to meet all geometric scenes of intersection of the sectional material and the plate, a basic library designer needs to perform personalized parameter definition on each type by contrasting a standard node diagram of the through hole, so that the configuration of the type of the through hole is greatly increased, and the workload and the difficulty of basic library design are greatly increased; on the other hand, when the structure designer applies the through holes, the structure designer also needs to compare with the standard node diagram and select the corresponding through holes for arrangement by combining through hole configuration, so that the design cost is increased, and the digital design elements of the ship cannot be embodied.
Therefore, the design mode of the through hole is urgently required to be improved, so that the design difficulty is reduced, and the design efficiency is improved.
