Moving the Point of Vertical Intersection for the
Ditches and Transitions
You can move the PVI (Point of Intersection) of a vertical curve by using the
Move PVI command. If you use this command after you design a vertical curve
for the PVI, then the command leaves the vertical curve and any labels in their
original positions. Erase the vertical curve, and then recreate it with the Vertical
Curve command.
To move the point of vertical intersection for the ditches and transitions
1 From the Profiles menu, choose DT Tangents รค Move PVI.
2 Select the tangents around the PVI you want to move.
Select these tangents in any order, and then press ENTER to continue the
command. The following prompt is displayed:
Station/Elevation/Both/Pick <Pick>:
3 Select the method of moving the PVI.
4 Enter the station and/or elevation according to the keyword option you use.
The command moves the PVI. The command holds the start point of the first
tangent and the endpoint of the second tangent. It modifies the grade values of
the tangents for the change in PVI location.
The following illustration shows moving a PVI:
