AI exposure: Mechanical Drafters
Prepare detailed working diagrams of machinery and mechanical devices, including dimensions, fastening methods, and other engineering information.
Reading this score
computed41.6% of this occupation's weighted task load is exposed, which puts Mechanical Drafters at the 74th percentile of 923 occupations. The capability is largely there. Its average task scores 2.5 out of 4 on what a current system can produce, and the frictions that hold other jobs in place are comparatively weak here.
What holds the line here is verification cost. Across this occupation's 16 tasks it averages 1.84 out of 3, the highest of the five friction dimensions. In plain terms, checking the output costs more than producing it. Where an undetected error is expensive, dangerous or irreversible, the economics change. Someone has to verify the work, and verifying can cost as much as doing it. This is the friction most likely to fall as tools for checking improve.
The most exposed thing this job does is Produce three-dimensional models, at 86.7%. The least is Supervise and train other drafters, technologists, and technicians, at 10.0%. A gap of 76.7% between two parts of the same job is the reason this index publishes at task level. An occupation-wide number would have hidden both.
Within architecture and engineering occupations, this one is more exposed than most. The median across the 56 roles in the group is 37.5%, and only 10 of them score higher than this. Occupational families are not uniform, and the spread inside them is often wider than the gap between them.
What would move this score. Of 16 tasks, 13 are currently banded exposed, 2 assisted and 1 untouched. For that distribution to shift materially would take a change in who is permitted to sign the work, which is a question for regulators rather than for engineers. The score is re-computed every quarter against a fresh capability reference, and the change is published rather than quietly applied.

Where the score comes from
judgedEvery task is scored through the standardised work activities it maps to. These are this occupation’s averages on the six rubric dimensions. Capability is what AI can do; the other five are what stands in the way.

| Embodiment | 0.06 | 0-3 |
| Presence | 0.44 | 0-3 |

What this means in practice
Where most of a role's weighted task load is exposed, the work that survives is usually the part of the job nobody wrote into the job description: deciding what should be produced rather than producing it, and being answerable for the result. The tasks lowest on this page are a better guide to where to spend your time than any general advice about the future of work.

Read this carefully. Exposure is not displacement. A high score means current AI systems can produce this work, not that anyone will stop paying a person to do it. Adoption depends on economics, regulation and inertia that this index deliberately does not model. How the score is built.
