Pathway Proximity Tolerance
A dedicated parameter in the Drawing tab of the User Settings dialog, called the Pathway Proximity Tolerance affects the range at which pathways are "visible" when routing cables or pathways.
This value represents the range between the Duct ends and any point on the Tray. Also, this is visualized when a pathway is selected - notice its ends (not continuation points) are displayed with dashed circles around them showing the proximity range.
