Agentic CAD describes systems that act inside the CAD workflow, such as editing geometry, automating repetitive modeling steps, roughing out first-pass concept geometry, or driving an existing CAD tool. These are more complex processes than just answering questions about a model. AI CAD review is the other side of the same coin, where AI can check a generated or modified design against manufacturability, inspectability, requirements, and cost. The more an agent produces, the more that checking matters, which is why the two work as a pair rather than as competitors.
