ArtisanCAD: An Industrial-Level CAD Agent with Expert-Grounded Knowledge Distillation

2026-07-07 · Source: Artificial Intelligence · Field: Technology & Digital — Artificial Intelligence & Machine Learning · Depth: Expert, quick

Summary

ArtisanCAD is a novel industrial computer-aided design (CAD) agent that addresses limitations in existing text-to-CAD methods, which struggle with ambiguous user prompts and underutilized expert procedural knowledge. This agent employs expert-grounded knowledge distillation, centered around its CAD intermediate representation (CAD-IR). CAD-IR serves two primary functions: distilling expert CAD procedures into reusable parameterized skills and providing a procedural scaffold to convert vague prompts into executable CAD operations. ArtisanCAD operates by retrieving these expert-derived skills, instantiating and revising CAD-IR, executing the procedure via a dedicated CATIA-MCP backend, and refining outputs using multi-view visual feedback to generate production-ready B-Rep models. On the Text2CAD benchmark, CAD-IR significantly improved generation from intermediate prompts, reducing mean Chamfer Distance from 14.83 to 9.88. It also successfully distilled expert CATIA recordings for complex automotive components, enabling the generation of editable CATIA-native B-Rep models for new variant requests.

Key takeaway

For CAD engineers or AI engineers developing industrial design solutions, if you are struggling with ambiguous text-to-CAD prompts or underutilizing expert procedural knowledge, ArtisanCAD offers a robust approach. You should explore integrating intermediate representations like CAD-IR to distill expert skills and scaffold vague design intents into executable operations. This can significantly improve the accuracy and editability of generated B-Rep models, as demonstrated by the reduction in Chamfer Distance from 14.83 to 9.88 on intermediate prompts. Consider adopting similar skill-guided, expert-grounded distillation techniques to enhance your automated design workflows.
