Create/Edit Corridor Baseline Dialog Box

Use this dialog box to create or edit a baseline for a corridor. The baseline can be comprised of an alignment and profile or a feature line.

Baseline Name

Specifies the format of the corridor baseline name. Click to open the Name Template dialog box.

Baseline Type

Specifies whether the baseline will be comprised of an alignment and profile or a feature line.

• Alignment and Profile: Specifies that the baseline will be comprised of an alignment and profile, and displays the Horizontal Alignment list so you can select the alignment.

  Horizontal Alignment

  Lists the horizontal alignments that are available. Click to select an alignment in the drawing.

• Feature Line: Specifies that the baseline will be comprised of a feature line, and displays the Site and Feature Line lists so you can select the feature line.

  Site

  Lists the sites that are available. Select a site from the drop-down list or click to select an object in the site in the drawing, which selects the site and filters the list of feature lines.

  Note: Leave this as <None> to list the feature lines that are not stored in a site.

  Feature Line

  Lists the named feature lines that are available in the specified site or that are outside of a site. Select a feature line name from the drop-down list or from the drawing. If you select the feature line from the drawing without first selecting a site, the site will also be selected.

  Tip: If a feature line is not named, it will not appear in the drop-down list. You can click to select a feature line (named or unnamed) in the drawing. If the selected feature line is not named, the Apply Feature Line Names dialog box is displayed so you can enter a name for it.

  You can select feature lines that have been created using the feature line creation tools, including dynamic or static feature lines that have been extracted from a corridor.

  Tip: Feature lines that have been extracted from a corridor and are either dynamic or static to that corridor can be selected for use as a baseline in the same corridor. For more information, see About Using Multiple Dynamic Baselines in a Corridor.
