The article deals with aspects of solving applied problems related to the capabilities of the automated COMPASS 3D system for geometric modeling of shipbuilding objects-vessel hull surfaces. The method for the ship's hull modeling based on flat curves, sections constructed on different offset planes is considered. A method is shown for improving the accuracy of the simulated frame surface of the ship's hull by introducing intermediate sections into the model frame. The concept of the modeling quality of the frame surface and the method of determining quantitative indicators for evaluating the frame surface quality are proposed. The practical implementation of the method of three-dimensional modeling of ship hulls is performed, and the comparative research results on the quality of the ship's surface modeling are presented.
