A sketch of the profile with 20 characteristic points is shown in Figure 1. Calculate the X and Y coordinates of all twenty points, relative to the PRZ. The coordinates of point 1 are: X1 = XPRZ + 0.5 - 0.5 Y1 = YPRZ - - 0.5 - 2 = -2.5 XI = 0.5 Y1 = -2.5 0.5 1.125 0.35 0.25 PRZ 0.5 116.5 27.5 0.25 35 4 3 50.
