Other names for these views include plan, elevation and section. These views are known as front view, top view and end view. Although six different sides can be drawn, usually three views of a drawing give enough information to make a three-dimensional object. In each, the appearances of views may be thought of as being projected onto planes that form a six-sided box around the object. The views are positioned relative to each other according to either of two schemes: first-angle or third-angle projection. Up to six pictures of an object are produced (called primary views), with each projection plane parallel to one of the coordinate axes of the object. In and, a multiview projection is a technique of illustration by which a standardized series of pictures is constructed to represent the form of a object.
