Parabolic Layout
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
and buttons and then re-computed with the button.
Current station
: is the station that will be solved for with the
button.
Elevation
: is the known elevation for the location(s) on the parabolic
curve where you want to compute the station(s).
: computes the details of the vertical curve.
: decreases the
Current station
by the
Interval
.
: increases the
Current station
by the
Interval
.
: computes either the elevation at the specified
Current station
or the station(s) at the specified
Elevation
.
