Based on the Ship Product Design (SPD) software, an efficient modeling system for guide rail of container ship is developed. The overall system architecture is established, and the system functions are realized with the key system technologies such as parametric component design of guide rail, local standardized component library construction of guide rail, knowledge-driven automatic layout of guide rail, and fast division of guide rail, and the application verification is conducted. The results show that the system can effectively improve the modeling efficiency and modeling quality of guide rail of container ship.
