Transparent viewing box

Assume that the object is placed in a transparent box, the faces of which are orthogonal to each other, as shown in figure 6.  Here we view the object faces normal to the three planes of the transparent box.

 

Figure 6. The object placed inside a transparent box.

When the viewing planes are parallel to these principal planes, we obtain the Orthographic views
The picture we obtain when the line of sight is projected on to each plane is called as the respective view of the object. The image obtained on the projection planes , i.e., on the top face, Front Face, and Right side face  are respectively the  Top View, Front view and Right side view of the object and is shown in figure 7.
