New in Corridor Workflows

Learn about enhancements to corridor workflows.

New in 2025.1

Improved the workflow for adding multiple baselines while editing corridors:

• The Create/Edit Corridor Baseline dialogue box is now the Add Baselines dialogue box and includes the multiple baseline selection tools available at corridor creation.
• Enhanced the functionality of the Pick from Drawing button in each baseline row. The alignment picker can select multiple alignments at once, and similarly, the feature line picker can select multiple feature lines in a single selection process.
• Select two types of baselines, including alignments/profiles and feature lines, during the corridor editing process.
• Expanded selection options for feature lines used as baselines: filter feature lines by Name, Style, Layer and Site to narrow down the selection scope.
• After multiple selection, you no longer need to press Shift or Ctrl to do multiple modifications.
• Added warning prompts when there are no feature lines meeting the preset filter.

For more information, see To add baselines to a corridor.

Improved performance when working with corridors includes the following optimisations:

• Cursor movement over large corridors with object snap enabled.
• Grip editing large corridors.
• Corridor feature line drawing/redrawing.

New in 2025

Improved performance in various areas of corridor workflows.

Corridor property dialog box enhancements

• Improved the efficiency of opening the corridor property dialog box.
• Improved the efficiency when clicking OK to close the dialog box.
• Improved efficiency when switching corridor property dialog box tabs.
• Improved performance when editing in the corridor property dialog box and then clicking Cancel to exit without making changes.

Other corridor property and parameter dialog boxes

These include Corridor Surface properties, Corridor Feature Line properties, Baseline and Region parameters, Codes and Slope Pattern.

• Improved efficiency when opening a child corridor properties dialog box for large corridors.
• Improved efficiency when clicking Cancel button to close a child corridor properties dialog box.

corridor surface creating

• Improved performance for building corridor surfaces that is 3 to 4 times faster than previous versions.
• Added the drawing level AeccFastCorridorSurfaceBuild system variable to control the methods of building corridor surface. A value of 0 is normal generation and a value of 1 is a faster generation at the cost of visual fidelity.
• Improved performance when deselecting a corridor surface on the Corridor Properties dialog box and the Corridor Surface dialog box.

Corridor updates to rebuild affected corridor sections commands

• Region grip editing in drawing.
• Split Region contextual (right-click corridor) or ribbon command.
• Merge Region contextual (right-click corridor) or ribbon command.

Corridor regeneration efficiency improvements

• Improved efficiency of the corridor section view editor by avoiding a slope pattern drawn in the section viewport.
• Improved efficiency by avoiding corridor surface and corridor section recalculation when a corridor is out of date. This improves the performance of commands like editing alignment or the profile of baselines of corridors.
• Improved regeneration efficiency for corridor feature lines.
