Edit Feature Settings - Corridor Dialog Box

Use this dialog box to view and change corridor-related settings.

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

• Drawing-level ambient settings are identified by the drawing icon.
• Corridor feature settings are listed near the top of this dialog box, after the General property group, and are identified by the corridor icon.
• Corridor command settings are identified by the command icon.

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

Lock Region To

Specifies whether to lock the corridor regions to either the geometry or chainage of the parent alignment:

Offset Target - Adjacent to Offset Target Start/End

Specifies whether the assembly should be inserted adjacent to the offset target start and end. This option creates chainages at a small offset before the offset target start and after the offset target end, rather than creating the chainages exactly at the offset target start and end. For more information, see About Changing the Frequency of Stations in a Corridor Region.

Offset Target - Along Offset Target Curves

Specifies how the frequency for inserting assemblies along offset target curves is determined.

• <None>: Does not add stations along offset target curves.
