To Change Alignment Station Control Properties

1. Click Alignment tabModify panelAlignment Properties drop-downAlignment Properties Find.
   Note: The tab most recently opened in the Alignment Properties dialog box is displayed by default.
2. In the Alignment Properties dialog box, click the Station Control tab.
3. Under Reference Point, click . The Alignment Properties dialog box closes.
   Important: Changing the reference point location or the reference station value removes all station equations and design speeds and can adversely affect objects and data already created from the alignment. Click OK to continue or Cancel to abort this operation. Use Station Equations to change stations after you create Profiles and Cross Sections.
4. In the drawing, pick a point where you want to establish the XY coordinates for the Reference Point. The Alignment Properties dialog box is displayed again.
5. In the Reference Point box, under Station, enter a starting station value.
6. In the Station Equations box, click . The Alignment Properties dialog box closes.
7. In the drawing, pick the point for the first station equation. The Alignment Properties dialog box is displayed again.
8. Repeat Steps 6 and 7 to add more station equations.
9. By default Station Ahead and Raw Station Back have the same value. Click the Station Ahead cell and enter a new value.
10. Click the Increase/Decrease cell to determine whether the station values from the Station Equation increases or decreases from the Station Ahead value.
