2 Enter the PVI station and elevation data in the Vertical Alignment Creation
Editor dialog box.
The starting and ending points of an alignment are considered PVIs. Tab
between columns. The % grade is calculated from the horizontal distance and
difference in elevation between the PVIs.
NOTE
The % grade is not an editable field in the Vertical Alignment Creation
Editor. However, you can edit the % grade when you return to the Vertical
Alignment Editor.
3 When you have finished entering the information, click OK to return to the
