Interactive 3D models and PMI simplify the collaboration process between OEMs and suppliers

In today's wave of digitalization sweeping through the manufacturing industry, model-based definition ( MBD ) technology is quietly reshaping the traditional collaboration methods of production supply chains, breaking the barriers of relying on 2D drawings and frequent file format conversions in the past.

Recently, Capvidia company launched a breakthrough browser 3D visualization solution, allowing suppliers to directly access interactive CAD models and product manufacturing information ( 3D PMI ). This technology combines standardized files with associated QIF/STEP visual models, providing procurement, manufacturing, quality departments, and workshops with a unified, authoritative, and user-friendly data view. HTML Breaking traditional collaboration barriers

01  The traditional "engineering drawing + 3D model" design and manufacturing mode can no longer meet the modern manufacturing industry's demands for high precision and high efficiency. 2D engineering drawings may cause data omissions and misunderstandings of design intent during product R&D, production, and manufacturing information transmission. Although a certain company of China Aerospace Science and Technology Corporation has transitioned from 2D to 3D in product design, the process design stage still uses traditional 2D process design mode, resulting in a significant digital gap between design and manufacturing.

02 The rise of MBD technology 2D Model-based definition ( ) technology uses a fully 3D digital model to fully express product design and manufacturing information, achieving a highly integrated manufacturing process. The model not only contains geometric shape information but also integrates product manufacturing information (dimensions, tolerances, technical requirements, etc.) and various attributes (design attributes, manufacturing attributes, classification attributes, etc.). CAD Aerospace engine manufacturing enterprises apply CAD technology to realize the use of 3D model data as the sole basis in the production and manufacturing process, achieving high integration of design, process, manufacturing, and inspection applications.

03 Breakthrough in browser interactive 3D models

The latest solution allows any browser to open interactive MBD models and MBD . This innovation means supplier teams no longer need expensive

-   significant results were achieved. Taking the formation tester EFDT dual-probe short section as an example, digital machining technology ensured one-time machining on the machine tool, shortening the machining cycle from FAI/PPAP days to

days, with a one-time machining success rate of various processed bodies reaching

, and product accuracy improved by an order of magnitude. MBD A certain company of Aerospace Science and Technology Corporation built a "process design and manufacturing system" to create a digital process innovation platform based on 3D models for process review, part process, assembly process, CNC process, and quality inspection process, solving the problem of inconsistent data in the integrated design and manufacturing process. 05 Application of mainstream MBD tool software The company's MBD MBDVidia 60 software 15 can publish standard-based 100% from native

These tools ensure the model's ). This technology combines standardized compliance with EFDT standards, human and machine readable, achieving true design-to-manufacturing-to-quality without manual transcription. MBD 。

06 Technical Implementation and Future Outlook

Implementation MBD Technology requires a systematic approach and organizational change. Practices of the Aerospace Science and Technology Group show the need to build bidirectional data pathways based on 3D model design between factories and institutes, - process - manufacturing and other development processes, realizing factory visualization under 3D processes, enhancing design and manufacturing iterative feedback capabilities.

Based on MBSE (Model-Based Systems Engineering) is regarded as a "revolution" and "future" of systems engineering. It uses formal modeling methods to support system requirements, design, analysis, verification, and validation activities, starting from conceptual design and continuing through all lifecycle stages.

CNOOC Service through MBD technology has reduced 05 Application of mainstream MBD tool software the machining cycle of dual-probe short sections from 60 days to 15 days. The Aerospace Science and Technology Group has built a digital process platform based on 3D models, achieving high integration of design, process, manufacturing, inspection, and other applications. Browser interactive 3D models are just the beginning. EFDT and STEP AP242 Open standards such as these will continue to deepen, running through the digital thread from conceptual design to quality inspection. Future manufacturing collaboration will require no manual drawing translation, no compatibility concerns, truly realizing model as standard, model as process, and model as collaboration.
