IntelliHull is a hull design technique which combines directly manipulating the surface definition and parametric hull design. It develops the hull form by lofting a single surface BSpline surface through a number of special BSpline curves know as IntelliCurves. The IntelliHull exposes a number of form parameters which when modified transform the definition curves changing the dimensions or hydrostatic properties of the hull surface. A bulb appendage can be added as an option using an additional set of parameters. IntelliHull was developed as a PhD project, more details can be found on the publications page of the PolyCAD website.


Right-Click -> Multiple Selection -> Create IntelliHull

Create an IntelliHull Surface by selecting two or more IntelliCurves.

The surface definition cannot be edited directly, but it can be manipulated by editing any of its attached IntelliCurve definition curves.
