Explanation:

The position of a point in engineering drawing is defined with respect to its distance from the three principal planes i.e., with respect to the vertical plane, horizontal plane, and profile plane.

The position of the object placed in any one of the quadrants is described below:

In the first quadrant - above the horizontal plane and in front of the vertical plane.
In the second quadrant - above the horizontal plane and behind the vertical plane.
In the third quadrant - below the horizontal plane and behind the vertical plane.
In the fourth quadrant - below the horizontal plane and in front of the vertical plane.

A point above HP and in front of VP (First Quadrant)

If a point is situated above HP then its front view is above the xy line and the distance of the front view from the xy line is equal to the distance of the given point from the H.P.
If a point is situated in front of VP then its top view is below the xy line and the distance of the top view from the xy line is equal to the distance of the given point from the V.P.

A point above HP and behind VP (Second Quadrant)

If a point is situated above HP then its front view is above the xy line and the distance of the front view from the xy line is equal to the distance of the given point from the H.P.
If a point is situated behind the VP then its top view is above the xy line and the distance of the top view from the xy line is equal to the distance of the given point from the V.P.

A point below HP and behind VP (Third Quadrant)

If a point is situated below HP then its front view is below the xy line and the distance of the front view from the xy line is equal to the distance of the given point from the H.P.
If a point is situated behind the VP then its top view is above the xy line and the distance of the top view from the xy line is equal to the distance of the given point from the V.P.

A point below HP and in front of VP (Fourth Quadrant)

If a point is situated below HP then its front view is below the xy line and the distance of the front view from the xy line is equal to the distance of the given point from the H.P.
If a point is situated in front of VP then its top view is below the xy line and the distance of the top view from the xy line is equal to the distance of the given point from the V.P.
