Application Analysis of Computer 3D Modeling Technology in Ship Design

With the rapid development of computer technology, people’s life has become more and more convenient, and it is widely used in all fields. Three dimensional modeling of ship structure is a very important research direction in ship design. With the development of computer-aided three-dimensional modeling software, the realization of rapid and intelligent hull structure design is of great and practical significance, which can improve the efficiency of ship design, speed up the progress of shipbuilding, and enhance the overall competitiveness of the shipbuilding industry. The traditional modeling method of hull structure 3D modeling is to build a small part of the hull segment with the help of some professional 3D modeling software. The workload is very large, not only need to consume a lot of human resources and material resources, but also low efficiency, also need to use skilled design software personnel. In this paper, solidwoks 3D design software, as a secondary development technology, is used as the platform of graphic expression. In the design process, microsor file is used to store, visual basic language is used to program, and several problems of 3D modeling of ship structure are studied. The 3D modeling software system of hull structure is developed to realize the rapid design of hull structure and generate the 3D model and engineering drawings of the target ship. This paper introduces a method of ship design automation based on three-dimensional modeling technology. It aims to study the method of quickly building three-dimensional model of ship structure, provide a set of three-dimensional design software which is in line with design specifications, simple to use and complete in function for ship structure design, and provide a new method for other three-dimensional modeling problems in ship design.
