Drawings do the communication best merely because a picture is worth a thousand words. Giving all of the information needed to make the product and being accurate in that information is the main goal. Engineers are very picky about their drawings and must pay attention to detail. One of the best ways to communicate ideas is through pictures, graphic illustration or drawings. Details of innovations and technical inventions are hid in drawing for the purpose of safeguarding them. Technical/engineering drawing is a means of communicating shapes, sizes, positions and proportion, features and precision of physical objects.
