### Transcript

• 1. Information in the drawing . Like a sketch, a mechanical drawing shows how an object should look. However, the drawing is made precisely to scale, and specifications of dimensions, angles, and other measurements are written on it. The drawing also provides instructions for producing the object. For example, a mechanical drawing of a gear may specify how precise the dimensions must be, the material and heat treatment to be used, the surface finish, and settings for the machines that are to fashion the gear from metal. Mechanical drawing definition is a drawing that provides the exact information needed to produce an architectural structure or a manufactured object. Every building, bridge, and dam requires mechanical drawings, as does every automobile, refrigerator, and lathe. Mechanical drawings represent the appearance of an object in different views. A view, also known as an orthographic projection, is made by drawing the various sides of a three-dimensional object on a flat plane such as the surface of a sheet of paper or a computer screen. In the United States, designers and drafters (specialists who prepare mechanical drawings) commonly use the isometric view , which consist of the top, front, and side views of an object.
