The profile tool’s edge counting operation is similar to the edge counting
operations for a gage tool, in the sense that they both return the number of
edges.
When the X direction is selected, the edge counting operation counts edges
along the X axis, as illustrated in Figure 7.131.

In Figure 7.131, the profile window is positioned over the pins on a 13–pin
connector, and it produces the profile display as shown. In this example, the
threshold has been set to gray scale level 87. At that level, the profile tool
detects only 24 edges (instead of 26), since it misses the broken pin.
When the workpiece is rotated 90
°, and the Y direction selected, the edge
counting operation will count edges along the Y axis.
