Purpose of AVEVA Initial Design Lines

Lines is a sophisticated hullform design system which enables Naval Architects to define and fair a hullform by means of a series of orthogonal and 3D space curves. Lines is capable of defining virtually any form of marine vessel including multi-hulls chined and asymmetrical hulls.

Input to the system is generally via an offset file, digitization of a preliminary lines plan. Once inserted, the hullform and its appendages can be developed by the progressive refinement of frame, Waterline, Buttock, 3-D angle curves and stem/stem profiles, which between them provide a complete three-dimensional wire frame definition of the hullform. Fairness can be checked by viewing these curves in the traditional manner, supplemented with several special features to assist in measuring fairness. The rapid development of hullforms is also aided by features such as 3-D curves, contracted fairing, special Waterline endings and hull distortion techniques, including sectional area curve transformations and parallel mid-body insertion.

Once defined, comprehensive lofting information including lines plans and loft books can be obtained for model or full scale production.
