What 3D CAD Modelers Do
Apply technical knowledge and skills in the use of three-dimensional (3-D) computer technology to create technical illustrations and models used in manufacturing, design, production, and construction.
Common Tasks
Architectural and Civil Drafters
- 1Produce drawings, using computer-assisted drafting systems (CAD) or drafting machines, or by hand, using compasses, dividers, protractors, triangles, and other drafting devices.
- 2Draft plans and detailed drawings for structures, installations, and construction projects, such as highways, sewage disposal systems, and dikes, working from sketches or notes.
- 3Coordinate structural, electrical, and mechanical designs and determine a method of presentation to graphically represent building plans.
- 4Analyze building codes, by-laws, space and site requirements, and other technical documents and reports to determine their effect on architectural designs.
- 5Draw maps, diagrams, and profiles, using cross-sections and surveys, to represent elevations, topographical contours, subsurface formations, and structures.
