DRAFTER, MECHANICAL
O*NET/SOC CODE: 17-3013.00 RAPIDS CODE: 0136
DESCRIPTION: Drafts detailed drawings of machinery and mechanical devices, indicating dimensions and tolerances, fasteners and joining requirements, and other engineering data: Reviews rough sketches and engineering specifications received from engineer or architect. Drafts multiple-view assembly, subassembly, and layout drawings as required for manufacture and repair of machines and equipment. Prepares working plans and detail drawings from rough or detailed sketches and notes for engineering or manufacturing purposes according to dimensional specifications: Calculates and lays out dimensions, angles, curvature of parts, materials to be used, relationship of one part to another, and relationship of various parts to entire structure or project, utilizing knowledge of engineering practices, mathematics, building materials, manufacturing technology, and related physical sciences. Creates preliminary or final sketch of proposed drawing, using standard drafting techniques and devices, such as drawing board, T square, protractor, and drafting machine, or using computer-assisted design/drafting equipment. Modifies drawings as directed by engineer or architect.
