AI CAD tools use artificial intelligence to help engineers create, analyze, review, or validate CAD models and drawings. Some AI CAD tools generate candidate geometry from prompts, constraints, or optimization goals, while others review existing designs for manufacturability issues, standards compliance, missing information, or design risks. The category includes generative CAD tools, AI CAD review software, AI-assisted simulation tools, and emerging agentic CAD systems that can perform actions inside existing engineering workflows.
