Lay out parts to prepare for assembly.

Lay out parts to prepare for assembly. is a detailed work activity in O*NET — a concrete unit of work shared across 5 occupations and seen in 5 occupation-specific tasks. It rolls up into the broader work activity Position materials or components for assembly. in Handling and Moving Objects .

Detailed work activities are the most granular shared layer in O*NET's work-activity hierarchy (Generalized → Intermediate → Detailed → occupation-specific task). The figures below describe how this activity shows up across the economy and what independent studies measure about AI and this kind of work — not a prediction that the work will be automated.

AI exposure

Of the 5 tasks under this activity that the OpenAI / Eloundou “GPTs are GPTs” study rated, 0 (0%) are flagged as directly exposed to language models (E1) or exposed via model-powered tools (E2).

Exposure estimates overlap with model capabilities — whether a model could speed the task up — not whether the work will be done by software. Observed AI use is augmentation and assistance today, not jobs replaced.

Member tasks

Occupation-specific tasks O*NET maps to this detailed work activity, most important first.

• Measure workpieces and lay out work, using precision measuring devices. · Grinding, Lapping, Polishing, and Buffing Machine Tool Setters, Operators, and Tenders, Metal and Plastic · importance 4.4 · no direct exposure
• Lay out and examine metal stock or workpieces to be processed to ensure that specifications are met. · Structural Metal Fabricators and Fitters · importance 4.3 · no direct exposure
• Lay out and fabricate metal structural parts such as plates, bulkheads, and frames. · Layout Workers, Metal and Plastic · importance 4.2 · no direct exposure
• Lay out and drill, ream, tap, or cut parts for assembly. · Engine and Other Machine Assemblers · importance 4.1 · no direct exposure
• Lay out, fit, or connect parts to be bonded, calculating production measurements, as necessary. · Welding, Soldering, and Brazing Machine Setters, Operators, and Tenders · importance 4.0 · no direct exposure
