Spiral Layout
The Spiral Layout screen is used to compute station locations on a
spiral curve.
Radius
: is the radius of the circular curve.
Spiral Length
: is the length along the spiral
curve from TS to SC.
TS station
: is the station at the TS point.
Interval
: When checked, is the spiral arc
distance that is added or subtracted from the
Current Station
using the and
buttons.
Current Station
: is the station on the curve that
is computed.
: solves and displays the details for the specified spiral curve.
: decreases the
Current Station
by the specified Interval.
: increases the
Current Station
by the specified Interval.
: computes the location of the
Current Station
.
Results
Station
: is the current
station.
Deflection
: is the
horizontal angle to the
current station as if
occupying the TS and
backsighting the Spiral
PI.
Long crd.
: is the chord
