Recently, the NURBS technique has been widely used in 3D design software for ships. However, most research, is only applied to mathematical representation of hull curves and surfaces, parametric deformation surfaces based on geometric feature parameters less understood. The aims this paper are establish process through classification curves, apply modeling finally achieve driven by develop soft...

Parametric optimization is an important product design technique, especially in the context of modern parametric feature-based CAD paradigm. Realizing its full potential, however, requires a closed loop between and CAE (i.e., seamless CAD/CAE integration) with automatic modifications simulation updates. Conventionally approach model conversion often employed to form loop, but this way working h...
