Figure 7. Multi-view drawing of the point lying in the third quadrant.

In the third angle projection, the  Top view is always above the front view and the  Right side view will be towards the right of the Front view.

Point in the Fourth quadrant

If A point is lying in the fourth quadrant, the point will be below the HP and infront of the VP. The point is projected on to the respective projection planes. After rotation of the HP and PP on to the VP, it will be observed that that the HP and VP are overlapping, similar to the second angle projection.  The multi-view drawing of objects in such case would be very confusing and hence fourth angle projection technique is not followed by engineers.
