3.5.3.3 
through both sets of plotted points. 
Although Figure 17 shows these results, 
the shipbuilder is provided with the large 
scale graphs so that he may have a more 
precise picture of the mismatches at the 
rolled surfaces. 
Fit in the Longitudinal Direction 
  
After the transformation described at the 
outset of paragraph 3.5.3 differences between 
longitudinal coordinates at corresponding 
points: directly indicate whether gaps or 
overlaps of the steel will occur. Analysis 
of a graphical presentation such as Figure 18 
allows the shipbuilder to determine whether 
advance corrective trimming will save time 
later. on during the joining maneuver. Of 
significance is that such data may also give 
insight as to locations where difficulties 
may occur. (due to excessive gaps) with the 
use of automatic welders. 
The Joined Centerline 
  
Since the last-mentioned transformation 
puts all coordinates in the same ship's 
coordinate system it is now possible to 
"see" the fairness of both portions of the 
centerline as represented by targets on the 
main deck level of both ship halves. The 
graphic illustrations of Figures 19 and 20 
are representative of presentations prepared 
for the shipbuilder.
