Five kinds of agents are already running in production engineering environments. CAD and drawing review agents read models and drawings, flag DFM risks and ambiguous notes, check title blocks and BOM consistency, and compare a design against your organization’s standards. Engineering search and decision-context agents pull up the feedback, standards, and past decisions behind a design so an engineer isn’t hunting for context before they can start. Agentic CAD agents act inside the CAD workflow itself, handling repetitive edits and roughing out first-pass geometry. Simulation setup agents interpret documentation and recommend boundary conditions to cut the time spent configuring an analysis. And lessons learned agents capture issues during reviews and resurface the relevant ones the next time a similar design comes around.
