Superelevation Diagram
The superelevation diagram, which is displayed in its own view tab, shows how the roads cross slope changes through each station in an alignment. Text and lines can be added to the diagram. Add a frame around an area of interest, then create a dynaview using the frame, to display the frames contents in the plan view or a sheet view.
To view a superelevation diagram, right click the alignment and select superelevation diagram from the context menu.
The diagram includes grid lines against which the superelevation profile is displayed. Vertical grid lines represent stations in the alignment. Horizontal grid lines represent degrees of slope. The two colored lines, which make up the superelevation profile, represent the inside and outside edges of the road.
The superelevation view is updated automatically as you make changes on the Superelevation tab.
If you have created a shareable slope table the shareable slope table profile will be displayed in the superelevation diagram. Select this profile to:
- edit the shareable slope table.
- edit the appearance of the shareable slope table profile.
- use the shareable slope table to define the slope in a template instruction.
See Create and Edit Shareable Slope Tables.
To configure the display of the superelevation template, use the Project Settings dialog.
