Mechanical Drawings

[Image]While every drawing executed by a CAD program is a mechanical drawing, this term is usually restricted to drawings representing machines, machine parts, and objects used in mechanic arts and trades. A mechanical drawing is the means that a machine or mechanical device is graphically shown by outlines, sections, and projections. object of a mechanical drawing may be to present the inventor’s idea for patent purposes, to convey to the prospective client the appearance and dimensions of a machine or part, or, more commonly, to transmit the designer’s idea to the machinist who creates and assembles the different parts to a complete whole mechanism or apparatus.

Mechanical drawings serve another important purpose which is giving a definite and visible form to the designer’s idea in order to assure them that the different parts will properly fit together and perform their intended functions.
