Objectives Regarding the traditional three-dimensional physical model of ships and two-dimensional principle drawings, there exist issues such as data fragmentation and difficulty in concurrent modeling, so 2D and 3D ship collaborative cabin layout technology is studied in this paper.

Methods First, by constructing a composite model oriented towards ship systems, the associated parameter sets of 2D and 3D models are automatically identified and configured. These sets encompass multi-dimensional information such as equipment geometric dimensions, spatial position coordinates, physical performance parameters, and the functional logic associations of ship systems. Then, on the basis of the principle diagram of the 2D schematic diagram, the intelligent correlation mapping algorithm is utilized to automatically achieve the precise mapping and dynamic update of equipment model in the spatial layout model. This process effectively enables the collaborative evolution of 2D and 3D models throughout the design phase. Finally, the validation of this technology was accomplished through the implementation of the cabin layout case.

Results The analysis targeted at the design cycle shows that by using the 2D and 3D collaborative layout system of ship equipment driven by the composite model, the layout efficiency is effectively increased to 4.5%, the feasibility and effectiveness of this technology in complex ship systems are fully verified.

Conclusions These research outcomes offer substantial technical underpinnings and valuable references for 2D and 3D ship collaborative cabin layout technology.
