Problem: A top view of a 75 mm long line AB measures 65 mm, while the length of its front view ~
is 50 mm. Its I.-lie end A is in the H.P. and 12 mm in front of the v.P. Draw the projections of AB
and determine its inclinatiion with H.P. and the V.P.

Solution: (Fig.5.3 8)

Fig. 5.38

1. Mark the front view al and the top view a of the given end A.


2. AssumingAB to be parallel to the v.p draw a line ab equal to 65 mm and parallel to xy. With
   al as centre and radius equal to 75 mm, draw an arc cutting the projector through b at bl. The
   line ffthrough bl and parallel to xy, is the locus ofB in the view and e is the inclination of AB
   with the H.P.
