Applying 3D product modeling technology to shipbuilding

Models created using 3D product modeling technology contain not only 3D geometry, but also associative, parametric relationships and non-geometric information. 3D product modeling technology provides the capability to create a ship model which increases in fidelity as the design matures and progresses from concept through detailed design, manufacturing and life-cycle maintenance. 3D product model data thus generated is available for close coupling of analysis with the CAD model, visualization, interference detection, and automated generation of associative bills ofmaterial and drawings. Through Simulation Based Design (SBD) technologies, 3D product models can be reviewed not only for engineering integrity, but also for producibility, manufacturability, and maintainability. A technical approach for quantifying the cost benefits of using 3D product modeling technology for shipbuilding is presented.
