Q.The projections of different points are shown in Fig. Define the position of the points in relation to the reference planes. The distances marked are in millimeters.

Q.The projections of different points are shown in Fig. Define the position of the points in relation to the reference planes. The distances marked are in millimeters.

SOLUTION:

(i) Point P is in both the VP and the HP. It lies in xy.

(ii) Q is 40 mm infront of the VP and 25 mm above the HP. It is in the first quadrant
ii) R is 20 mm behind the VP and 50 mm above the HP and hence is in the second quadrant.

(iv) S is 40 mm in front of the VP and in the HP. It is between the first and fourth quadrants.

(v) T is 35 mm above the HP and in the VP. That is, T is between the first and second quadrants.

(vi) U is 25 mm behind the VP and 35 mm below the HP and hence lies in the third quadrant.
