Introduction
With the gradual application and promotion of 3D computer-aided design (CAD) technology, and the application of model-defined design (MBD) technology in manufacturing...
Within enterprises, 3D digital models have gradually replaced 2D engineering drawings, becoming the core data carrier in the product development process. This shift...
This change not only reflects the evolution of technological forms, but also signifies a profound transformation in product design methodologies and management models. Because 3D models are crucial in technological information...
The data management and document control methods differ significantly from the traditional two-dimensional model in terms of information expression, data organization structure, and collaborative management.
The process also faces systemic restructuring.
To adapt to the development approach centered on 3D digital models, this system addresses the bottlenecks in product design data management within a 3D environment.
The problem is to promote the popularization and engineering application of model-based definition technology, support the digital transformation and upgrading of my country's manufacturing industry, and formulate...
GB/T 46848 "Requirements for the Management of Product Design Data in Technical Product Documentation". GB/T 46848 is based on the entire lifecycle of product design data.
The management process is planned to consist of nine parts.
---Part 1.General Provisions. The purpose is to stipulate the general rules for the classification, compilation, archiving, copyright, and protection of product design data.
It serves as the foundation and framework for the entire series of standards.
---Part 2.Numbering Principles. The purpose is to define the general principles, basic requirements, and numbering methods for product design data files.
This method ensures the consistency and traceability of data file identification.
---Part 3.Basic Procedures. The purpose is to define the main stages and basic processes of product design data formation, as well as its completeness and...
Standardized review requirements ensure that the data generation process is standardized, orderly, and controllable.
---Part 4.Access Control. The purpose is to define the classification, setting methods, and requirements for product design data permissions, ensuring data security.
Access and operations are secure and controllable.
---Part 5.Document Management. The purpose is to define the classification and coding, creation and compilation, review and approval, and issuance of product design data documents.
Release, change management, storage and maintenance, retrieval and access, ensuring the consistency and effectiveness of document management.
---Part 6.Product Structure Management. The purpose is to define the working environment, hierarchical division, creation methods, and node details of the product structure.
Capacity, node attributes, status control, usage requirements, and BOM management requirements ensure the relevance and reusability of the product structure.
---Part 7.Approval and Issuance. The purpose is to define the basic principles, general requirements, and detailed requirements for the approval and issuance of product design data.
The document outlines the distribution methods and requirements for product design data to ensure the standardization and authority of data review and distribution.
---Part 8.Change Management. The purpose is to define the principles, classifications, content, and requirements for changing product design data.
Requirements, including numbering management, version management, access control, storage and maintenance, etc., to ensure that the data change process is controlled and reliable.
To trace back.
---Part 9.Storage and Maintenance. The purpose is to define the classification, general requirements, and detailed procedures for data storage and maintenance management in product design.
The requirement is to ensure the security, availability, and integrity of data during long-term storage.

3 Terms and Definitions
The terms and definitions defined in GB/T 46848.1 apply to this document.
4.Classification of Storage and Maintenance
Based on different management methods, the storage and maintenance of product design data can be divided into the following two categories.
a) Information system management, such as using a computer document management system or a PDM system;
b) Manual management, such as using storage media like USB flash drives, hard drives, and optical discs.
5 General Requirements
5.1 Product design data should be stored and maintained using computer-based document management systems, PDM, or other information systems.
5.2 Stored product design data should be signed completely and meet the requirements of integrity and consistency.
5.3 Stored product design data files shall be numbered and named in accordance with the requirements of GB/T 46848.2.
5.4 The product design data media should be properly stored in an environment with a temperature of 14℃~24℃ and a relative humidity of 45%~60%.
It should also be kept away from magnetic fields, heat sources, and places with harmful gases such as acids and alkalis.
5.5 Two-dimensional drawings generated from the projection of the three-dimensional design model should be stored together with the three-dimensional model and kept in association.
5.6 Changes to the 2D drawings should be driven by modifications to the 3D design model.
