Approaches for compartments modeling in ship CAD software

Abstract

As part of the project to create a Russian independent computer-aided design system for ships, the presentation of geometric data in a structured form is an urgent issue. The article presents the scientific and applied research, which systematize and expand knowledge about the formalization of information on the geometry of the vessel surface and its premises for performing design calculations and modeling operations using previous design experience and existing calculation techniques. The task of presenting a scheme for the formation of premises for a ship's computer-aided design system has been solved to achieve this purpose. A presented approach bases on the concept of "dissecting" surfaces, which implies the continuity of data at any stage of design. To indicate the "boundary" surfaces of the room, is possible to use an interactive method, that is, to determine the surfaces in the spatial model of the vessel by pointing at them on the monitor screen. The bounding planes for this type of assignment are described. The advantage of formalizing geometry data is the operability and continuity of the ship's computer-aided design system that will be maintained at any moment of its development, and digital continuity of design will be ensured.
