Arc Edge Locator Setting the Position Constraint Function Editor Score Threshold The score threshold sets the minimum acceptable score for a valid edge. The tool will disregard edges that obtain a score lower than the Score Threshold. l Scores attributed for constraints range from 0 to 1. l If both Position and Magnitude constraints are enabled, each constraint accounts for 50% of the total edge score. Sort Results You can enable the Sort Results checkbox to sort the located edges in des- cending order based on values. By default, Sort Results is not enabled and edges are output in the same left to right order as they appear on the pro- jection curve.
