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

.
