AVEVA Initial Design 12.0

Geometry - Lines

Lines is a hull fairing tool for creating virtually any form of marine vehicle, including multi-hulls, chined and asymmetrical hulls. The hull form is initially represented as a loosely-connected mesh of curves that is used to semi-automatically create a surface comprised of B-spline patches and bounded planes with tangential (C1) continuity. Advanced mathematical techniques are incorporated for automatic curve fairing and surface smoothing. The quality of the surface can be assessed using isophotes to visualise fairness and continuity. Lines can be used for rapid hull form creation in preliminary design, or for full production fairing.
