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 Sta + and Sta – buttons.
Current Station: is the station on the curve that is
computed.
Solve : solves and displays the details for the specified
spiral curve.
Sta - : decreases the Current Station by the specified
Interval.
Sta + : increases the Current Station by the specified Interval.
Layout : computes the location of the Current Station.
