Parabolic Layout
&XUYH 3DUDEROLF /D\RXW 
The Parabolic Layout screen allows you to compute an elevation at a
specified station, or a station at a specified elevation.
Beg. Grade : is the percent grade at the PVC.
End Grade : is the percent grade at the PVT.
Curve Length : is the horizontal distance between
the PVC and PVT.
PVC Station : is the starting station at the PVC.
PVC Elevation : is the elevation at the PVC.
Solve for : is where you select to solve for an
unknown Elevation , or an unknown Station . The
selection made here determines which of the
following choices will be available.
;
Interval : When checked, the Current station can be incremented by
the specified interval by using the
6WD  and 6WD  buttons and then
re-computed with the
/D\RXW button.
Current station : is the station that will be solved for with the
/D\RXW
button.
Elevation : is the known elevation for the location(s) on the parabolic
curve where you want to compute the station(s).
6ROYH : computes the details of the vertical curve.
6WD  : decreases the
Current station by the Interval .
6WD  : increases the
Current station by the Interval .
/D\RXW : computes either the elevation at the specified
Current station
or the station(s) at the specified Elevation .
