In the manufacturing process, 3D models are revolutionizing the design concept of 2D drawings!

"One-time stocking, multiple deliveries," engineers from Hongyu Precision's digital intelligence development department no longer suffer headaches over chaotic drawing versions. They log into this year's 2 domestically developed independent MBD platform, where 3D models directly drive warehouse distribution processes, improving on-time rates at line-side warehouses 20% and above. In traditional manufacturing workshops, 2D drawings were once the sole authority. Workers repeatedly consulted paper documents, with dimension tolerance annotations crowding the page edges; design changes meant redrawing, and version management was a nightmare.

01  Intelligent disassembly, MBD technology reconstructs design logic

3D models are replacing static drawings with dynamic and interactive advantages. A research team from Shanghai University of Science and Technology developed the BANG system, which uses "generative explosion dynamics" technology, through AI deep learning to understand object structural logic, allowing 3D models to automatically decompose into parts and generate exploded views.

Compared to traditional surface segmentation methods, BANG it can handle internal structures, generate complete volumetric parts, and improve processing speed by more than 8 times. Designers input language commands, and the system can intelligently disassemble tens of thousands of parts of engines and precision instruments.

The core breakthrough of this technology lies in converting parameters such as 3D spatial coordinates and sketch normal angles into learnable language Tokens enabling AI understanding of complex geometric relationships. This marks a shift in design from planar annotation to spatial intelligent reasoning.

02 Tool evolution, mainstream platforms achieve seamless integration

Global industrial software giants compete to build MBD ecosystems. 2025 Year 6 Month, PTC launched Onshape cloud-native MBD features, becoming the first solution to embed product manufacturing information ( PMI ) in a cloud-based CAD platform. Engineers can access 3D annotation data in real time on any device.

SOLIDWORKS 2025 module achieves revolutionary simplification of the annotation process. Designers directly convert sketch-driven dimensions into MBD 3D PMI (Product Manufacturing Information), with wedge dimension functions synchronously generating angle and width parameters. Domestic toolchains are also making great strides. The KMCloud platform built by Kaimu Software achieves full-chain linked updates from whole machine parametric definitions to part modeling through

TopDown skeleton-driven design. Shiguan Technology's GCKontrol tool focuses on automotive electronic control, meeting model development and code generation under the ASPICE standard. 03 Cross-modal generation, AI reconstructs design entry points Generating precise models from text descriptions is no longer a fantasy. A team from Zhejiang University developed an algorithm that runs efficiently on the Ascend

NPU

to convert sparse sketches into editable Img2CAD models. Designers' casually drawn outlines instantly become 3D data usable for CNC machining. PMI Even more remarkable is the emergence of This multimodal large model achieves end-to-end generation from text and images to construction sequences, reducing the median Chamfer Distance

(a key metric measuring model accuracy) to CAD-GPT , which is a reduction of / . The parameter accuracy rate reaches PMI 98.12% with an invalid model rate of only 1.61%. 9.77 Industrial design is entering an era of "what you see is what you get." GPT-4 04 Manufacturing implementation, full-chain data closed loop 84% Value continues to be released on the manufacturing side. The Hongyu Precision project shows that after implementing an intelligent supply chain based on 3D models: compliance rate for first-in-first-out of chemical raw materials reached and the full-process data traceability response time shortened In the aviation field, Aura Aero uses

functions to digitally certify aircraft parts, compressing the cycle from concept to production by

MBD 3D models have become the sole data source for design, process, and inspection. 98% Capvidia's 70%。

MBDVidia Aura Aero公司利用 Onshape module achieves revolutionary simplification of the annotation process. Designers directly convert sketch-driven dimensions into MBD 功能，100%数字化认证飞机零部件，从概念到生产周期压缩40%。三维模型成为设计、工艺、检验的唯一数据源。

Capvidia公司的MBDVidia Platform overcomes key bottlenecks. This software supports Siemens NX 、 PTC Creo and other mainstream PMI systems, achieving QIF standard bidirectional interoperability of 3D annotation data. Design changes are fed back to inspection programs in real time, completely eliminating distortion from 2D drawing conversions.

Professor Zhang Longwen's team in BANG system papers predicted: "Generative explosive dynamics will reshape product cognition." As CAD-GPT etc. AI tools break through the technical bottleneck from text to modeling, allowing designers to instantly generate manufacturable models by describing "aluminum alloy housing with cooling holes."

Siemens NX and Capvidia collaboratively established QIF data closed loop has been validated in the Boeing supply chain: 3D annotation data goes directly to inspection equipment, with automatic alarms for tolerance exceedances. Global 30% aviation parts suppliers plan to eliminate 2D drawings by 2026 years ago — this design revolution from "paper talk" to "three-dimensional combat" is accelerating into the depth of the industry.
