In the Alignment's contextual ribbon tab, click on the Superelevation drop-down
Select the Calculate/Edit Superelevation command
If the alignment does not contain any superelevation data a task dialog will be displayed with the following options.
Calculate superelevation now - choose this option to open the superelevation calculation wizard
Open the superelevation curve manager - choose this option to open the superelevation curve manager, where you can view curve data.
NOTE: After the initial superelevation calculation, the Calculate/Edit Superelevation command automatically displays the Superelevation Curve Manager.
In the task dialog select Open the superelevation curve manager > Tabular Editor > Import Superelevation data from file > locate theappropriate CSV file > click open.
NOTE: If there is existing superelevation data, you receive a warning that existing data will be overwritten.
Click OK. The Superelevation Tabular Editor will now display the descriptions and values for each region.
NOTE: After calculating the superelevation, any changes to the alignment geometry e.g. adding, deleting, or moving a curve is reflected in the Superelevation Tabular Editor. However, changing the radius of a curve will cause the superelevation data to become out of date and will have to be recalculated.
