Recently, Mr. Huang Tao, the Technical Director of Zhongwang 3D China, shared his insights in an interview about the challenges and future of full 3D application in China's manufacturing industry. As a seasoned professional with extensive experience in mold design and over eight years in CAD/CAE/CAM/PLM systems, he has played a key role in promoting 3D software adoption across various enterprises and research institutions. His thoughts on the current state and future of 3D technology are both insightful and practical.

1. Many companies have adopted 3D design software, but the level of implementation varies widely. What should companies do to make 3D design software truly effective?
In my view, the effectiveness of 3D design software largely depends on whether a company clearly understands its product development needs and the specific problems it aims to solve through 3D CAD. Choosing the right 3D software is crucial. Once the software meets the design requirements, it’s important to implement top-down management support and plan the integration based on the company’s actual situation. This process should be carried out systematically, with clear responsibilities assigned at the supervisory level. Ensuring proper technical resources will help ensure that 3D CAD is fully integrated into daily operations.
2. Why is the adoption of 3D CAD in enterprises slow, and what role do technical standards play in this? What are some established standards, and where should companies start when developing their own?
The development of 3D technical specifications and standards plays a vital role in the successful implementation of 3D CAD. Having such standards makes the process much smoother. For example, the national standard "GBT 25108-2010 3D CAD Software Functional Specification" outlines basic functions like 3D modeling, parts libraries, assembly, engineering drawings, and data exchange. However, while these standards are comprehensive, they are often not deep enough for most companies to apply effectively.
Because different 3D CAD software have unique features and modeling approaches, it’s challenging to create universal standards. Therefore, I recommend that companies develop internal standards tailored to their specific needs and the 3D CAD tools they use. Collaboration with software suppliers can also help in creating more relevant and practical guidelines.
3. After adopting 3D CAD, many companies still face issues with 2D documents and legacy drawings. How can this problem be resolved?
Two main factors contribute to this issue: first, many companies have accumulated a large number of 2D drawings from long-term use of 2D CAD, and after switching to 3D, they haven’t taken steps to gradually convert these drawings. Second, some companies use separate 2D and 3D software, which leads to inefficiencies. When 3D designs are converted to 2D formats and imported back into 2D software, it creates a disconnect between the two systems.
To address this, companies should use the built-in 2D functions of 3D software instead of relying on separate 2D tools. This ensures better synchronization and reduces errors during design changes. It also streamlines workflows and improves overall efficiency.
4. How can advanced design methods like modular design support the transition to full 3D processes and improve efficiency and customer satisfaction?
Modular design involves grouping product elements into functional subsystems that can be reused across different products. This approach allows companies to reduce development costs and speed up time-to-market. However, implementing modular design requires robust 3D software that supports such methods. Companies must invest in the right tools and ensure their teams are proficient in using them. Many modern 3D software solutions already include features to facilitate modular design, making it more accessible for manufacturers.
5. What does a fully 3D-enabled enterprise look like, and how close is China’s manufacturing industry to paperless workshops and digital factories?
A fully 3D-enabled enterprise goes beyond just design—it integrates 3D throughout the entire product lifecycle, including production, manufacturing, and management. Currently, only a small number of companies have reached this level. Achieving paperless workshops and digital factories requires strong leadership, advanced information systems, and significant investment in both software and hardware. For many Chinese manufacturers, this remains a distant goal. While progress is being made, the road to full 3D adoption in China’s manufacturing sector is still long and challenging.
