||Layout Workers, Metal and Plastic
- Mark curves, lines, holes, dimensions, and welding symbols onto workpieces, using scribes, soapstones, punches, and hand drills.
- Compute layout dimensions, and determine and mark reference points on metal stock or workpieces for further processing, such as welding and assembly.
- Design and prepare templates of wood, paper, or metal.
||Structural Metal Fabricators and Fitters
- Mark reference points onto floors or face blocks and transpose them to workpieces, using measuring devices, squares, chalk, and soapstone.
- Locate and mark workpiece bending and cutting lines, allowing for stock thickness, machine and welding shrinkage, and other component specifications.
- Design and construct templates and fixtures, using hand tools.
||Drilling and Boring Machine Tool Setters, Operators, and Tenders, Metal and Plastic
- Establish zero reference points on workpieces, such as at the intersections of two edges or over hole locations.
- Lay out reference lines and machining locations on work, using layout tools, and applying knowledge of shop math and layout techniques.
- Operate tracing attachments to duplicate contours from templates or models.
||Patternmakers, Metal and Plastic
- Assemble pattern sections, using hand tools, bolts, screws, rivets, glue, or welding equipment.
- Construct platforms, fixtures, and jigs for holding and placing patterns.
- Lay out and draw or scribe patterns onto material, using compasses, protractors, rulers, scribes, or other instruments.
||Model Makers, Wood
- Plan, lay out, and draw outlines of units, sectional patterns, or full-scale mock-ups of products.
- Fabricate work aids such as scrapers or templates.
