This paper studies the application of computer-aided technology in the design of complex surface structures of ships, analyzes the characteristics of complex surface structure design, describes the design process of complex surface structures, and focuses on the study of surface unfolding technology based on computer-aided design. It compares the application effects of B-spline method and NURBS method in expressing complex curves and surfaces, and proposes an implementation method of adaptive mesh optimization algorithm. It is also compared with traditional mesh division, and the results show that the adaptive mesh division enhances the expression of complex surface structure details and effectively reduces the design error.
