Background
Mbd (model Based definition), model-Based product digital definition. The MBD labeling method realizes that the design facing to the manufacture does not depend on a two-dimensional engineering drawing any more, but a single data source for design and manufacture, namely the three-dimensional model with the labeling information.
In the traditional ship development process, a design unit delivers a design result to a construction unit in a two-dimensional engineering drawing mode, and the construction unit performs production lofting according to needs in a production link. In the production lofting stage, a building unit can translate a two-dimensional engineering drawing into a three-dimensional model, and due to the difference of design processes of different building units, the same two-dimensional engineering drawing brings different sets of lofting results, so that the design unit needs to modify a large number of two-dimensional drawings according to different opinions of the building unit. A great deal of modification work still cannot avoid the result that final deliveries of the same product designed by a design unit are different, and the result causes different objects of the same product type, thereby bringing great trouble to users.
Along with the requirements of shipowners on the performance of various aspects of ship equipment, the requirement of fine design is increasingly prominent, and in the face of increasingly severe international situation, the high quality, short cycle and multi-aspect collaborative product development requires the high-quality and high-requirement digital transformation of the ship direction. In the current digital design of ships, model-based statistics and mapping are not limited to statistics of the number, length and weight centers of gravity of models and simple projection of models, which can reduce part of workload, but because the model is not a single data source, designers still need to spend a great deal of time and effort in field coordination and editing and modifying map information in the later stage, so that the whole process needs to be optimized.
