Draw the projections of a point A lying on HP and 25mm in front of v.P.

Solution:

1.  Point A is lying on H.P and so its front view allies on xy line in Fig . Therefore, mark a line xy in the orthographic projeciton and mark on it a^l (Fig.5.1 Ob). 
2.  Point A is 25mm in front ofV.P and its top view a lies on H.P itself and in front of xy. 
3.  Rotate the H.P through 90° in clock wise direction, the top view of the point a now comes vertically below al .
4.  In the orthograpl;tic projection a is 25 mm below xy on the projector drawn from a^l.
