A scaled multiview drawing of a three-dimensional object to show each view separately, in a series of two-dimensional drawings, for example, top or bottom, front, back and sides. In Australia, orthogonal drawings use third-angle projection for layout of the views. Orthogonal drawings may also include measurements on each view and are used to develop lists of material requirements. In these drawings each edge is represented by a connected line, each segment of which is parallel to a coordinate axis. Also see production drawing.
