It shows two or more two-dimensional views of a three-dimensional object. It provides the shape description of an object. When combined with dimensions, these drawings serve as the main form of communication between designers and manufacturers.

• Isometric

• Oblique

• Perspective

• Multi- View

This type of perspective is relatively simple to make, but is somewhat awkward in appearance when compared to other types of pictorials .It has one vanishing point.

• Three Point Persepctive

• Two - Point Perspective

• One Point Perspective

• Isometric Drawing

The distance from front to back of an object is called its

• Length

• Height

• Width

• Depth

A rough drawing representing the main features of an object or scene and often made as a preliminary study.

• Freehand

A proportion between two sets of dimensions used in developing accurate, larger or smaller prototypes, or models of design ideas is called scale.

• True

• False

This term means equal measure.

• Isometric

• Perspective

• Multiview

The relationship of one thing to another in size. Good sketching is the ability to estimate size, distance, angles, and other spatial relationships is proportion and estimation.

• True

• False

A form of pictorial sketch in which all three drawing axes form equal angles of 120 degrees with the plane of projection are called Oblique Drawings

• Lenght

This is an imaginary line that is used to locate or project the corners, edges, and features of a three-dimensional object onto an imaginary two-dimensional surface.
