3.2 Orthographic Projection
Orthographic projection is a collection of 2-D drawing that work together to give an
accurate overall representation of an object. Different views of an object are projected
on different planes observing perpendicular to the respective reference plane. The best
views are selected using Six Principal Views (Figure 3.1) which are most descriptive of
object and normally, the longest dimension is chosen as the width (or depth). The most
common combination of views is to use are front, top and side view.
