Edit Feature Settings - Intersections Dialog Box

Use this dialog box to view and change intersection-specific settings.

This topic documents settings in all intersection-related Edit Settings dialog boxes (drawing-level, feature-level, and command-level).

• Drawing-level ambient settings are identified by the drawing icon.
• Intersection feature settings are listed after the General and Labeling property groups, and are identified by the intersection icon.
• Intersection command settings are identified by the command icon.

For information about drawing-level ambient settings, see Ambient Settings Tab (Drawing Settings Dialog Box).
