In the practice of replacing 2D drawings with 3D models, these key factors must be well grasped!

A seemingly ordinary annotation on a design drawing can cause a workshop to shut down for three days and result in losses of hundreds of thousands of yuan—the ambiguity of 2D drawings is becoming a fatal bottleneck in modern manufacturing.

With the global manufacturing industry transitioning towards intelligence, model-based definition ( MBD ) technology is rapidly replacing traditional 2D drawings. According to Fortune Business Insights forecast, BIM (Building Information Modeling, MBD applied in the construction field) market size will surge from 2025 billion USD in the year 91.2 to billion USD. 2032 billion USD in the year 220.8亿美元。

However, the transformation process is not smooth.

01  Pain points of 2D drawings

Traditional 2D drawings expose increasingly serious problems. In the power cable industry, engineers deeply feel: "3D technology produces actual projected shapes, but to comply with 2D engineering drawing standards, special processing is required, often with unsatisfactory results."

This leads to three core issues:

Insufficient visualization makes it difficult for designers to understand spatial relationships; inconsistent coordination causes cross-department communication barriers; frequent revisions lead to chaotic drawing versions.

"Using 2D drawings and sketches in early design stages plants problems that cause rework and delays on site." Industry reports point out that outdated tools cause high error rates and lengthy processes.

A lesson from an automotive parts supplier is particularly profound: unclear 2D drawing annotations caused interference during assembly of mass-produced parts, directly resulting in order losses amounting to 370 hundreds of thousands of yuan.

02 MBD Tool Innovation

Key technologies solving these pain points are breaking through. 2025 In the year, mainstream CAD MBD platforms have strengthened

functions: SOLIDWORKS 2025 achieved revolutionary simplification of the annotation process. Designers can now directly convert driving dimensions in sketches into 3D PMI (Product Manufacturing Information), avoiding repeated annotations.

More breakthrough is the newly added "wedge dimension" feature, which can simultaneously generate two dimensions: angle and width, greatly improving design efficiency.

CAPVIDIA company developed FormatWorks for SOLIDWORKS 、 MBDConnect for Creo 、 MBDConnect for NX three plugins supporting mainstream mainstream systems to directly publish models compliant with QIF standards, MBD achieving three core functions: automated generation of FAI First Article Inspection reports, CMM measurement operation automation, and direct import of measurement results into the MBD model. The Belgian CAPVIDIA company, since its establishment in the year, 1994 has focused on solving verification and inspection technical challenges for companies like Boeing and Airbus. Its tools ensure CAD/CAM PMI annotations comply with (Quality Information Framework) standards. QIF （质量信息框架）标准。

03 Key Points of the Transformation Path

Implementation of MBD transformation requires grasping three key dimensions:

Data connectivity is fundamental. Currently, most enterprises face the dilemma of "each tool being an information island." Among domestic brands, ZWSoft's 3D unified underlying core achieves parameterized conversion of heterogeneous mainstream data through geometry modeling engine and data conversion engine.

Personnel adaptation is a challenge. A mechanical industry website survey shows: "Directly handing 3D drawings to the field cannot be achieved in the foreseeable next few years." This stems from inertia in education systems and work habits—engineers receive professional education based on 2D drawing production.

Phased implementation is a pragmatic strategy. ZWSoft product director Hu Qideng proposed a four-level maturity model: 2D drawing centered → 2D/3D parallel → model-based definition ( MBD ) → model-based enterprise ( MBE ).

Currently, domestic 70% manufacturing enterprises are still at the 2D/3D parallel stage, with only leading companies beginning to try pure MBD models.

04 Future Ecological Outlook

Leading enterprises have built complete MBD workflows. Shenzhen Xunpeng Technology's ESOP-3D system demonstrates the future vision: this system integrates design, production, and management, achieving full lifecycle digital management through 3D modeling and virtual simulation.

Its value chain presents three major advantages: real-time updates of design changes to the model; digital models directly connected to CNC machines; real-time monitoring of production status to reduce downtime.

Domestic mainstream Software is catching up. ZWSOFT 3D All-in-One CAx The platform breaks through cloud-based 3D models, focusing on connecting PLM system integration bottlenecks, solving the "data silo" problem.

Hu Qideng pointed out: "Under the new quality productivity background, digital transformation is the foundation for enterprises to build sustainable innovation. Domestic mainstream needs to grasp the core demands of China's industrial sub-sectors and promote customers to surpass traditional technology models."

QIF Standards, as the framework running through design to manufacturing inspection, are quietly spreading in Chinese manufacturing. They adopt XML as the foundation, supporting information integration at the design, measurement, and manufacturing ends, and are key enablers of industrial 4.0 smart manufacturing.

Boeing and Airbus suppliers have long adopted MBD technology to handle complex assembly issues. When surface treatment symbols annotated on 3D models automatically update to ISO 21920 standards, and measurement data is fed back to the design model in real time, workshop disputes decrease 65% , and quality inspection efficiency improves. 40%。

The future belongs to enterprises that treat 3D models as the "single source of data." As domestic mainstream platforms break through data conversion bottlenecks, small and medium-sized manufacturing enterprises will find digital paths suitable for themselves—this is no longer a technology race but a survival necessity.

3D models are not the end point but the starting point of the digital thread!
