In chapter 9, layout of orthographic projections was presented, Front view is drawn above the reference axis XY and the top view is drawn below the reference axis XY, where XY is the intersection of horizontal and vertical planes.

In perspective projection, the object is shown as it appears to the human eye, but the true shape and size cannot be seen.

Perspective projection is an another way of representing an object on a plain paper. So far we have seen orthographic projection and isometric projection.
