How do I change the design stage of my corridor?
The functionality to change the Corridor Design Stage from SELECTSeries 4 has been replaced with assigning a Feature Definition to the corridor in OpenRoads Designer. You change the Feature Definition of the corridor by going to it's Properties and selecting from the drop down menu. The screenshot below shows the Feature Definitions provided with the delivered workspace.
These Feature Definitions that define the Corridor Design Stages are located in the Explorer > OpenRoads Standards > Feature Definitions > Corridor.
