Extracting chord widths from scans

Needing help once again! I am scanning leading edge and trailing edge of a blade at the given height (cross-section)the gage calipers are not repeating very well.. how should I go about pulling the farthest point of each scan to give me the chord width? I considered maxindex but the sections twist along the blade so they are not aligned to the axis. would constructing a circle of the two scans hit the two highest points?
PS currently waiting for $25k approval for PCDMIS blade. Hopefully that will make life easier!
