ShipLINES produces a B-Spline surface of a single-screw cargo ship hull form with and without bulb based on 25 geometric parameters. Most of these are used to define local appendages such as the bulb and shaped skeg. The control polygon of the hull surface is specified directly around the areas of the stem, midship section, transom and skeg. The rows of the surface are blended in between taking account of the parallel middle body.


Menu: Create -> ShipLINES

When the ShipLINES hull surface is created it is initially ungenerated. The surface can be updated from the attributes panel.

Interactive Editing

A ShipLINES hull surface is edited by changing the numerical parameters in the attributes panel. The updating can be made interative by checking the 'Interactive update' box in the parameters group of the attributes panel.
