Abstract

In the draft of the 4th generation NPS the designer submitted a 3D-model of the hull structures to the factory for lofting preproduction for the first time in the practice of the CDB.
In the three years, the experts of the CDB "Sevmash" developed the lofting documentation for the submarine of the 4th generation, on the basis of 3D modeling using proprietary software and including the designs of bow, superstructure, fence cuttings, feed stabilizers and NFM products. The list of the developed documentation includes: the details sketches, the information necessary for the production of offset table bending tooling, contouring sketches, information for making assembly beds patterns.
The documentation was transferred to the steel-plant both in hard copy and electronically via the corporate network. Currently, to minimize paperwork, the sketches of the details are transmitted electronically only, in the pilot normal mode 110 As a result of this work the following tasks have been accomplished:
• automation of the development and formation of the PDD according to the models;
• automation of the technological development of parts of the drawing;
• PDD developed on a design for testing;
• Graphical information prepared for the process of fencing felling structures formation on the stocks;
• according to the actual misalignment of Article 24 the real position of the wavebreaker shield cutouts was determined, and the proposals on the finalization of the hull structures were made to the designer.
The release of the PDD based on the information of 3D models using our own software (2011-2014) allowed:
• to reduce the duration of lofting preproduction;
• to improve the quality of the development of the design documentation and PDD;
• to come to construction agreements at the modeling stage;
• to considerably reduce the adjustment work during assembly;
• to reduce the workload of the Plaza and the technological service department for the production of steel-PDD on the commissions of other 4th generation submarine projects.

Keywords: 3D-modeling, preproduction, design documentation, automated documentation release.
