Enhancements

Corridor Workflows

• Added support for creating multiple baselines while generating corridors:
• Select multiple baselines during corridor creation.
• Select two types of baselines, including alignments and profiles/feature lines, during the corridor creation 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.
• Edit multiple baselines and assemblies during corridor creation.
• Note: when editing multiple baselines and assemblies, the shift key needs to be pressed continuously.
• Add code set styles during corridor creation, eliminating the need to edit the corridor after creation.
• Change multiple assemblies in the Parameter Tab or Corridor Properties Dialog.
• This allows multiple changes to assemblies for regions under the same baseline or for different baselines.

New in Dynamo for Civil 3D

• Dynamo core version has been updated to Dynamo 2.19

New API Enhancements

• Added the ability to call the API to export C3D objects to the ArcGIS FileGeodatabase to automate workflows from Civil 3D to ArcGIS.
