Surface Modeller (A001)

The surface modeller enables the designer to develop a surfaced-based geometrical definition of their ship or submarine. This license configuration includes functionality to support simple geometrical types such as Non Uniform Rational B-spline Surface (NURBS) entities, planes, polylines, etc.

For surface ships there is the QuickHull methodology to assist in rapidly developing hull surfaces with desired form properties and shaping. This uses some boundary B-spline curves and rescales them to fit within user specified key points. A surface is then fitted to this data and distorted to fit the required Cross Sectional Area curve.

For submarines there is the SWIFT methodology to form the external shape from first principles based on inviscid flow theory. Using a combination of sources and sinks it is possible to rapidly create a streamlined surface for the outer form of the submarine.

There is also a family of objects to enable 2D drawings to be constructed which can interrogate solid models to provide deck plans, tank tops, slices ready to put into reports or to take into other CAD software. There is also a powerful set of objects to handle reports generated from the software to maintain the configuration control.
