| Abstract | In the initial stages of ship design, designers represent geometly, aπangement, and dirnension of hull structures with 2D geometric primitives such as points, lines, arcs, and drawing symbols. However, these dεsign information('2D geomeσic primitives') defmed in the drawing sheet require more intelligent translation processes by the designers in the next design stages. Thus, the loss of design semantics could be occurred and following design processεs could be delayed. In the initial design stages, it is not easy to adopt commercial 3D CAD systems, which have been developed for being used in detail and production design stages, because the 3D CAD systems require detailed input for geometrical definition. In this study, a semantic product model data structure was proposed, and an initial sπuctural CAD system was developed based on the proposed data sσucture. Contents('product model data and design knowledges') of the proposed data structure are filled with minirnal input of the designers, and then 3D solid model and production material information can be automatically generated as occasion demands. Finally, the applicability of the proposed semantic product model data structure and the developed initial structural CAD system was verifiε:d through application to deadweight 300,000 ton VLCC(Very Large Crude oil Carrier) product modeling procedure. |
