Description
The MEASURE_DIRECTION option was chosen for the Calibration Direction parameter, but there were invalid measure values on some of the polyline features in the input polyline feature class. As a result, the Calibration Direction parameter's value was changed to DIGITIZED_DIRECTION for those polylines.
Solution
Examine the log returned with the tool run, and identify which polyline features have the issue. Edit the vertices of those polylines and ensure that they have proper measures.
