Technical drawing, also known as technical drafting or drawing, is the discipline of composing drawings that communicate how something functions in a visual sense. A technical drawing is vital for communicating ideas in engineering and industry. To make the drawings easier to understand, people make use of familiar symbols, units of measurement, perspectives, notation systems, page layout, or visual styles. Together, such conventions make up a visual language that helps ensure that the drawing is unambiguous and relatively easy to understand. Many of the principles and symbols of technical drawing are codified in an international standard referred to as ISO 128.
The need for precise communication in preparation for a functional document separates technical drawing from the expressive drawing of the visual arts. Artistic drawings are interpreted on a subjective level and their meanings are multiplied and determined by each person individually. Technical drawings can only have one intended meaning. A drafter, draftsperson, or draughtsman is the person that is responsible for making a drawing. A professional drafter who solely makes technical drawings is sometimes also referred to as a drafting technician.
Their job opportunities range from being employed in civil and construction work to the field of software engineering where they are required to create designs for software companies.
