Parabolic Curve Layout

The Parabolic Curve Layout screen is useful to compute the locations

of any station along a vertical curve when two parts of the curve are

already known. The values computed can be written down and used

to later stake those stations in the field.

1. Tap Curve , Parabolic Curve from the Main Menu.

2. In the Known field, select if the station and elevation

for the PVC or the PVI are known by selecting the

appropriate radio button. Also specify if the Curve

Length, Point on Curve, or High/Lo Elevation is known

from the dropdown list. (The remaining information

that must be entered will vary depending on the

choice made here.)

3. Fill in each field with the remaining information that

pertains to your parabolic curve and tap Solve.

Note: The length of a parabolic curve is the horizontal

distance from the PVC to the PVT.

Note: The horizontal distance from the PVI to the PVC always equals

the horizontal distance from the PVI to the PVT
