Design and Implementation of A CAD Software System for Hull Lines

摘要

A CAD software system for hull lines based on .NET is introduced in terms of system construction and principle. The system adopts a 3D V-shaped fairing computing model, which sufficiently considers the consistency of lines offsets in three different projection planes. By means of tree structure for parametric hull lines and 3-dimensional modeling technology, the system supports total-process-design of hull lines. Such a system not only can draw main parameter table, lines offsets table and lines plan grid automatically, support interactive design and synchronous adjustment for hull lines, but also can cut the hull synchronously and produce the 3-dimensional model of the hull. The implementation of this CAD software system for hull lines improves the hull design efficiency and quality.
