Problem: A line AB of 25 mm long is perpendicular to V:P and parallel to H.P. The end
points A and B of the line are 10 mm and 35 mm in front of V:P respectively. The line is 20 mm
.' above H.P. Draw its projections.
Solution : (Fig.531)
Fig.5 .31 a shows the position of the line AB in the fIrst quadrant. As the line is parallel to H.P., the
length of the top view is equal to the true length of the line and the front view appears as a point.
Figure 5.31b shows the projection of the line.
