This registry entry determines whether or not the software attempts to detect and snap to the nearest edge when placing target anchor points on the Vision tab. This is implemented when the value is set to TRUE.
If you have a blurred edge that can’t be brought into focus, you may find it necessary to switch this off to reliably specify anchor points when programming a feature.
Entry Name: SnapToEdge
Entry Type: TRUE or FALSE value. The default value is TRUE.
