Before calculating superelevation data, you need to ensure that required settings and styles are specified correctly.
| Specify a design speed | Specify a design speed in the alignment properties. A design speed is necessary to calculate superelevation. |
| Specify superelevation label defaults and verify default label abbreviations | Review the superelevation critical point label options on the Abbreviations tab in the Drawing Settings. Review the default label abbreviations for geometry points and superelevation critical points. |
| Verify alignment feature settings | Review the alignment feature settings for Superelevation Options and Dynamic Alignment Highlight Options. |
| Customize criteria files | Customize the criteria files using the Design Criteria Editor. Superelevation is calculated based on these files. |
| Review profile view band properties | Specify the Profile View band properties for superelevation data. |
| Create the alignment | Create an alignment to use for superelevation calculations. |
| Optionally, add user-defined curves | Add user-defined curves from the Superelevation Curve Manager. Add curves for situations where a curve is not automatically created by the program, for example where an alignment has two compound spirals or a compound transition in between spirals. Curves can be added after calculating superelevation data but you have to re-calculate the superelevation. |
