Technical drawing allows efficient communication among engineers and can be kept as a record of the planning process. Since a picture is worth a thousand words, a technical drawing is a much more effective tool for engineers than a written plan.

Fields of Use

Technical drawing is the preferred method of drafting in all engineering fields, including, but not limited to, civil engineering, electrical engineering, mechanical engineering and architecture.

Importance of Accuracy

Precision is of the utmost importance in all technical drawing, as drafts in all fields of engineering are expected to be scaled, labeled and arranged exactly as the final product would be. For this reason, technical drawing is always performed with tools such as compasses, T-squares and shape templates.


Because of the importance of accuracy in any technical drawing, the use of CAD, or computer-aided design programs, is becoming increasingly common. These programs increase the speed and accuracy of the drafting process, as well as making the reproduction of drafts as simple as printing text documents.
