The CadWin, SigamaNest and alma software realize the mode of combining the automatic nesting service and the manual interaction nesting service, and the AVEVA and SPD software adopt the mode of interaction nesting. Except that SPD is a domestic software with proprietary intellectual property rights, the rest of SPD belongs to foreign software. With the vigorous popularization and application of SPD software in domestic shipyards, shipyards applying SPDs basically introduce foreign automatic nesting software to make up for the business deficiency. However, due to the adoption of different systems, data conversion and data maintenance are required, and the problems of loss of part data and error and leakage of part groove information often occur. In addition, repeated conversion of nesting data is caused by part design change (material, shape, lane and the like), and comparison information cannot be effectively provided and automatically updated, so that the workload of workers is increased. In addition, as the whole material and the excess material library are designed and need to be updated and managed continuously, the phenomenon that the nesting plate cannot be found after the nesting instruction is issued due to information lag is caused.

The SPD is domestic industrial software for designing and building the ship body, wherein an interactive nesting module of the SPD is widely applied to a plurality of shipyards, and mainly realizes the functions of generating structural parts of the ship body, interactively nesting, generating a nesting plate diagram, generating a nesting plate cutting instruction and the like. With the development of IT technology, the development of Internet of things technology and the development of intelligent cutting equipment, the SDP realizes that automatic jacking becomes a business function module which is urgently needed by ship body construction design, so that the accuracy of data is improved, the information loss in the data conversion process is reduced, and the working efficiency is improved.
