Abstract: To improve the efficiency and accuracy of 3D hull modeling, address data fragmentation issues when exporting hull models from different software, reduce the data volume of hull surfaces, and better support hydrodynamic performance calculations and experimental model fabrication, this paper proposes a hull modeling method based on offset points and lines plan using CATIA V6. A technical system is established for repairing defective hull models, reconstructing surfaces, and verifying quality. A series of EKL programs are developed for rapid hull modeling. CATIA V6 offers powerful logical and professional capabilities, making it well suited for modeling marine engineering series models. The development and summarization of hull modeling methods based on CATIA V6 are of positive significance for the overall design of ships.
