Measure from the center of the Center Ball to the center on the 10th Ball
on the right then measure from the center of the Center Ball to the center
of 10th Ball on the left.
NOTE: The distance from the Center Ball to the 10th Ball should be the same ±1.5mm.
Now check the shadow ball by clicking the Vertical Line from point icon
from the measurement toolbar. (Figure 12)
