3d cad simplification method of equipment and materials of ship outfitting and offshore plants

The present invention relates to a method for simplifying 3D CAD data of marine shipbuilding materials comprising a simplification reference defining step for defining a simplification reference for the simplification of the 3D CAD data of the materials by applying an algorithm generation unit which generates a feature shape rearrangement algorithm of a marine shipbuilding vessel or marine plant materials; a data format defining step for defining data format for inputting the 3D CAD data by using a data format unit; a determination and calculation step for determining a priority by considering specifications which comprises at least one of volume, a port, and a main material size with a determination and calculation unit and developing a calculation formula; and a module performing step for performing a module which simplifies the 3D CAD data of the materials with a module performing unit. The present invention is provided to automatize a process for building the 3D CAD data of vessel and marine plant materials by defining the simplification reference of the 3D CAD data and providing the simplification algorithm based on the defined simplification reference, thereby reducing the building costs and the time for a shipbuilding company and a related company.
