Mechanical drawing


Drawing of mechanical subjects, done by a draftsman with the help of mechanical tools or instruments, such as a compass and a T-square. More of this kind of drawing is being done with the use of computers than in the past, and is then referred to as computer graphics or computer assisted design (CAD). This is the opposite of freehand drawing. Also see applied arts, commercial art, cross-section, draftsmanship, fabricate, French curve, line, linear, perspective, plan, and scale.
