Question
Problem 9.13 A 70 mm long line PQ does not have H.T.
and V.T. One end of the line is 30 mm in front of the V.P.
and 20 mm above the H.P. Draw its projections.
Interpretation As the line PQ does not have H.T. and
V.T., it is parallel to both H.P. and V.P.
Construction
Refer to Fig. 9.13.
1. Draw a reference line xy. Mark point p' 20 mm above
xy and point p 30 mm below xy.
2. Draw a 70 mm long line p'a' parallel to xy to repre-
sent the front view.
