Draw the projections of a point A lying on v.p and 70 mm above HP

Solution:

1.  Looking at the pictorial view from the front (Fig) the point A is 70 mm above H.P and so a^l is 70 mm above xy. Hence, mark a^l the orthographic projection 70 mm above xy 
2.  Looking at the pictorial view from the top, point a is on V.P and its view lies on xy itself. The top view a does not lie on the H.P. So in this case the H.P need not be rotated. Therefore mark a on xy on the projector drawn from a^l .
