CADD systems allow drafters to create and store drawings electronically so that they can be viewed, printed, or programmed directly into automated manufacturing systems. CADD systems will also permit drafters to quickly prepare variations of a design. Many drafters use CADD extensively but it is only a tool.
Drafters will need knowledge of traditional drafting techniques, in addition to CADD skills and manual drafting and sketching may also be necessary skills for use in certain applications.
Drafters drawings include technical details and specify dimensions, materials, and procedures and drafters fill in technical details using drawings, rough sketches, specifications, and calculations made by engineers, surveyors, designers and architects.
Drafters will use their knowledge of standardized building techniques to draw in the details of a structure and also use their understanding of engineering and manufacturing theory and standards. Technical handbooks, tables, calculators, and computers are also used in their work
