Prepare detailed working diagrams, drawings, and computer models of mechanical devices, parts, and assemblies, including dimensions, fastening methods, and other engineering information.
Drawings/models include various views, sectional profiles, irregular or reverse curves, hidden lines, and small or intricate details.
Work requires use of most of the conventional drafting and Computer Aided Design (CAD) techniques and a working knowledge of the terms and procedures of the occupation.
Work requires the ability to perform arithmetic computations using formulas.
Prepares complete sets of complex drawings or computer models that include multiple views, detail drawings, and assembly drawings.
Drawings or models include complex design features that require considerable drafting skill to visualize and portray.
Assignments regularly require the use of mathematical formulas to draw contours or to compute weights, center of gravity, load capacities, dimensions, quantities of material, etc.
Works from sketches, computer models, and verbal information supplied by an engineer or designer to determine the most appropriate views, detail drawings, and supplementary information needed to complete assignments.
Selects required information from computer programs, and internet sites, precedents, manufacturers' catalogs, and technical guides.
Independently resolves most of the problems encountered.
Supervisor or design originator may suggest methods of approach or provide advice on unusually difficult problems.
