The figure 10.11 depicts parallel projections.
Figure 10.11 Parallel Projections
Orthographic Projections
Engineering drawings often use front, side, and top orthographic views of an object. Figure 10.12
illustrates the three orthographic views of an object.
Figure 10.12 Orthographic Views
Orthographic projections that show more than one side of an object are called axonometric orthographic
projections. An isometric projection is the most basic type of axonometric projection, where the
projection plane intersects each co-ordinate axis in the model co-ordinate system at an equal distance.
This projection is a method used to show an object in all three dimensions in a single view.
