View and edit cant data for each curve.
For a description of the formulas that are used to calculate the values in this dialog box, see About Cant Variables and Formulas.
Collapses all items in the tree view.
Expands all items in the tree view.
Specifies a station along the alignment. Select a row in the editor and click , the tabular editor temporarily closes and the command line prompts you to pick a station along the alignment.
Deletes the selected region or station.
Recovers the most recently changed data in the Cant Tabular Editor.

This column displays the Transition In Regions and Transition Out Regions for the curves in the alignment.
Expand each region to view or edit the cant parameters.
To manually add a new critical station, right-click a region or a parameter Add Station.
Critical Stations include:
Displays the start station and end station of each transition region. When you edit these fields for a Transition In Region, Transition Out Region, or a critical station, the Length field is updated. If the critical station you edit is the same as the Start Station or End Station of a Transition In Region or Transition In Region, that station value is also updated.
Displays the length for the Transition In Region and the Transition Out Region.
Displays the warning symbol for areas on the alignment where there is overlap. Click the , and a task dialog box is displayed showing the options to resolve overlap. The conditions are either a reverse curve situation or a compound curve situation. To automatically resolve overlap you can select the option on the Calculate Cant Wizard - Attainment Method Page. However, there can be situations where overlap is created by manually editing cant data.
Specifies the applied cant value (in mm or in.) that was specified on the Calculate Cant Wizard - Attainment Method Page.
Specifies the result (in mm or in.) of the Equilibrium Cant calculation for a given speed and radius of curvature
Specifies the difference (in mm or in.) between Equilibrium Cant and Applied Cant.
Specifies the cant gradient value (rise:run), which is the ratio between the difference in cant from the current critical station to the next critical station, and the length of the transition.
The speed (in m/s or ft/s) that is applied upward in a curve.
The rate (in m/s^2 or ft/s^2) at which centrifugal force is applied outward from a curve.
