Baseline and Region Parameters Dialog Box

Product Documentation
Intermediate
View Original

Use this dialog box to specify new corridor region parameters, including baselines, regions, and controlling offsets

This dialog box is displayed when the Set Baseline and Region Parameters box is selected in the Create Corridor dialog box.

Expands all baseline categories.

Collapses all baseline categories.

Turns on all baselines.

Turns off all baselines.

Add Baseline

Adds another baseline (alignment) to the corridor definition.

Set All Frequencies

Opens the Frequency to Apply Assemblies dialog box, where you can specify the increments at which assemblies are placed along tangents, curves, spirals, and other geometry points.

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. If you subsequently add an assembly region that uses the same set (or subset) of targets, the mappings are automatically assigned. For more information, see Setting and Editing Targets.

Note

If targets are required and not set, messages are displayed in the Event Viewer. To display the Event Viewer, click GeneralUtilitiesEvent Viewer. For more information on the event viewer, see The Civil 3D Event Viewer Vista.

The properties 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 beside the baselines and regions 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

Opens the Select An Assembly dialog box where you can select an assembly for the corridor region.

Start Station

Specifies the start station for the 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 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 baseline or region. Click to open the Frequency To Apply Assemblies dialog box, where you can modify the station frequency and manually add stations.

Target

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

Overrides

This field is disabled when you are creating a corridor. For more information, see Viewing and Deleting Overridden Stations.

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.
