On the sixth day of CADD Care, the CADD team gave to me… advanced Corridor Transitions in Civil 3D!
Since the release of Civil 3D 2023, corridors have seen a ton of new roadway design features added and old workflows overhauled. Look no further than the new and enhanced Corridor Target dialog boxes and functionality. One of the more impressive additions to the corridor object is the new ability to create and edit Corridor Transitions. These transitions can be used when you want to transition or change a parameter in a subassembly.
The Corridor Transition panorama vista allows the user to select a supported subassembly parameter and to apply a new parametric value to that value. To increase the detail and functionality of this tool, the transition between the parameters can be dialed in. The transition types include: Linear, Bay Taper, Cubic In/Out, Parabolic In/Out, and Reverse Parabolic. These new transitions can allow users to create more complex corridors without the need for additional targeting geometry being created or intricate overrides setup. Additionally, this is a simpler method than using the existing Section Editor and parameter overrides and can be exported from Civil 3D and applied to other corridor designs and projects as a template.
Example CSV Export for simple transition:
Once exported from Civil 3D, the corridor transition is easily editable in Microsoft Excel or a text editor. This allows users to add additional details to the corridor transition design and to append additional transisions to the existing baseline. By simply modifying the CSV transition file curb returns can be placed at all required locations along the corridor:
