After running the Transpose Element command to modify and reverse a horizontal geometry, the profile doesn't seem to be reversed. The annotation appears to reverse for the geometry but the directional arrows and profile do not change.
When running the Geometry > Horizontal > Modify > Transpose Element command, the program will create a copy of the original element for the transpose. When the Transpose Element command is run, you will see a new / additional Alignment geometry get added to the OpenRoads Model. What has likely happened is the Profile View opened is for the original base geometry. You need to isolate and open the profile view for the correct geometry, which would be the newly created transposed alignment.
In the image below, the 'original element' is the alignment Geom_BL. The transposed alignment created is Geom_BL1. Both of these geometries exist in the OpenRoads Model, so it could be that the element selected for the Profile model is still the original element. Since these elements are located on top of each other, it may be difficult to visually verify which element Profile Model is opened, so you would need to either open the profile model by right-clicking on the geometry in the Explorer > OpenRoads Model and opening the profile view, or you can look at the name of the Profile view to verify it matches the correct horizontal geometry which should be opened.
