arXiv:2606.01702v1 Announce Type: cross Abstract: Deep learning in computer-aided design (CAD) remains fundamentally constrained by the data scarcity challenge: authentic CAD data is difficult to collect at scale, while synthetic data may not faithfully reflect real design practice. Rather than pursuing ever-larger CAD datasets, this paper alternatively treats CAD learning as a knowledge completion and calibration problem. It introduces KDH-CAD, a knowledge-data hybrid framework that integrates pretrained knowledge in foundation models, structured domain knowledge from textbooks/tutorials, and
The proliferation of foundation models and increasing demand for efficient design automation coincides with the persistent challenge of data scarcity in specialized domains like CAD.
This development offers a potential breakthrough for AI application in engineering and design, reducing reliance on massive datasets, and accelerating innovation in hardware development and manufacturing.
The approach to AI in CAD shifts from pure data-driven methods to a hybrid model that leverages existing knowledge, potentially making AI more accessible for niche, data-poor industries.

- · Companies reliant on large proprietary CAD datasets
More sophisticated and efficient AI-powered design tools become available to a broader range of engineers.
The cost and time required for product development in complex industries could significantly decrease, fostering greater innovation.
This hybrid approach might generalize to other data-scarce domains, fueling AI adoption where it was previously impractical.
