Parameters Tab (Corridor Properties Dialog Box)

Expands all baseline categories.

Collapses all baseline categories.

Turns on all baselines.

Turns off all baselines.

Add Baseline

Adds a baseline (alignment) to the corridor definition.

Set All Frequencies

Opens the Frequency To Apply Assemblies dialog box, where you can map targets from subassembly definitions to appropriate drawing object names for the entire corridor.

Set All Targets

Opens the Target Mapping dialog box, where you can map targets from subassembly definitions to appropriate drawing object names for the entire corridor. For more information, see Setting and Editing Targets.

The parameters table contains the following columns:

Name

Displays a tree listing all baselines, regions, and corresponding offset alignments.

Note

Offset alignments are displayed if the assembly is defined with assembly offsets. For more information, see Creating an Assembly Offset.

The check boxes next to the baselines or region names specify whether to show (selected) or hide (cleared) the baselines or regions. If the check box is cleared, that section of corridor is not reprocessed when underlying elements (for example, alignments, subassemblies, or surfaces) change.

Note

The check boxes have a tri-state display. If only one of the regions is selected under a baseline, the check box is dimmed and unavailable.

Alignment

Specifies the alignment for a baseline or offset alignment. Click this field to open the Pick Horizontal Alignment dialog box where you can select an alignment.

Profile

Specifies the profile for a baseline offset alignment. Click this field to open the Select A Profile dialog box where you can select a profile.

Assembly

Specifies the assembly for the corridor region. Click to open the Select An Assembly dialog box where you can select an assembly.

Start Station

Specifies the start station for the corridor region or controlling offset. By default, for the first region added to a baseline, this value is set to the start station of the baseline. If one or more corridor regions already exist, this value is set to the end station of last region. Enter a value or click to select a location in the drawing area.

End Station

Specifies the end station for the corridor region or controlling offset. By default, for the first region added to a baseline, this value is set to the end station of the baseline. Enter a value or click to select a location in the drawing area.

Frequency

Specifies the frequency at which assemblies are placed for a given region. Click this field to open the Frequency To Apply Assemblies dialog box, where you can modify the station frequency and manually add stations.

Target

Opens the Target Mapping dialog box, where you can modify the mapping of targets from subassembly definitions to appropriate drawing object names. For more information, see Setting and Editing Targets.

Overrides

Opens the Corridor Parameter Override Stations dialog box, where you can view and delete assembly overrides to stations in the selected region.

Select Region From Drawing

Selects a region in the drawing to display in the parameters table.

Lock Regions To

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

• Geometry Locking: Locks corridor regions to the alignment geometry. If the alignment is modified, the corridor region start and end stations are updated to maintain the region location relative to the alignment geometry.
• Station Locking: Locks corridor region start and end stations to the corresponding alignment stations. If the alignment is modified, the corridor region start and end stations are maintained, even if the region must move geometrically.
