For a CAD engineer, acceptance criteria is mainly an ownership decision. The page should make clear what this role approves, what it only prepares, and who receives the asset next.
For CAD engineer, write pass-or-fail conditions that another reviewer can repeat. Attach the tested file, destination version, observed result, and owner rather than approving the asset from screenshots alone.
Write observable pass conditions for the role, including what can be approved directly and what must be escalated. Apply this acceptance criteria guidance to the actual CAD engineer delivery path.
