2. Click Alignment tabModify panelSuperelevation drop-downCalculate/Edit Superelevation Find.
   Note: The first time you use the Calculate/Edit Superelevation command on an alignment that contains no superelevation data, a superelevation curve is calculated for each curve (circular arc) in the alignment. A task dialog is displayed with the following options:

   • Calculate Superelevation Now - choose this option to launch the Superelevation Calculation wizard.
   • Open The Superelevation Curve Manager - choose this option to open the Superelevation Curve Manager, where you can view curve data.

     After the initial superelevation calculation, the Calculate/Edit Superelevation command automatically displays the Superelevation Curve Manager.

3. In the Superelevation Curve Manager, expand the Superelevation Criteria node and make necessary changes.

   The Superelevation Status changes to Out of Date.

4. Click Recalculate to update the superelevation.

Note: The following parameters may be changed without causing the superelevation data to become out of date:

• Pivot Method
