Drafting: Drawing Our Future

Drafters create technical drawings based on information from engineers, architects, and designers/technicians. Manufacturers and construction workers use the drawings to produce and build something as small as a hearing aid part to something as large as a skyscraper.

Drafters sometimes draw by hand, using T-squares, triangles, and drafting tables, but usually use Computer Aided Drafting (CAD), that is, they draw via computers using drafting-specific software such as AutoCAD, Microstation, Chief Architect, and others. Drafters often specialize in one or more disciplines, e.g., mechanical, electrical, civil, structural, or architectural drafting, becoming experienced in specifications, standards, and codes that apply to a design. They fill in the details that take a design from an engineer’s or architect’s sketch to a document that includes not only various views of an object, but detailed notes about materials, maintenance access, building/manufacturing methods, and how the piping, circuits, etc. on the drawing interface with those found on other drawings. On the computer screen, drafters can rotate a 3-dimensional object to show the customer a realistic picture of the end product. Drafters utilize software to determine materials quantities and attributes needed for a project, for example length of piping or volume of fill dirt. Drafters also assist engineers, designers, etc. in exploring dimensional options and deciding on the best fit.

A Drafter’s skill in visualizing objects from different angles helps the Drafter perform a “reasonableness check” on a design concept. His drawing accuracy enables procurement personnel to order correct quantities of materials and helps minimize rework in the field or factory during construction and manufacturing. Drafters are the bridge that links concepts and regulations/requirements to actual devices, networks, and structures.
