Evidence stage
CapabilityA demo, benchmark or paper shows the task can be done. Updates what the technology can do — not what employers will do.
Tasks this bears on
Checking drawings against codes and standards
Checking drawings for consistency, dimensions, symbols and compliance with codes and drawing standards before they go out.
Being augmented≈ Platform inference
Where this applies
A benchmark of questions on mechanical drawings tested multimodal large language models. The authors find the models brittle on mechanical engineering drawings, where dense annotations, weak domain knowledge and unreliable spatial reasoning under projection rules make decisive cues easy to miss. A preprint benchmark; it measures reading drawings in a test, not work in drawing offices.
What this means
General AI models cannot yet be trusted to read a mechanical drawing correctly.
What it does not yet show
One benchmark, a preprint; models change quickly.
What you can check
Open arXiv:2605.30794 and find "brittle on mechanical engineering drawings".
Does it change the assessment?
No — and this stage does not move it either. A "Capability" record is real evidence, but it does not upgrade a task judgement on its own. The 1 linked judgement above stand where they were.
