length from the TS to the current station.

Short crd.

: is the chord length from the previous station to the

current station.

Traverse on Spiral

The Traverse on Spiral screen is used to compute the location of, and

optionally store the SC, or ST and spiral PI points.

Radius

: is the radius of the circular curve.

Length

: is the length along the spiral curve

from TS to SC.

CS Point

: is the existing point associated

with the TS or CS point.

/ : is the tangent direction

at the TS or CS point.

TS->SC

: specifies that the curve starts at the

tangent to spiral and ends at the spiral to curve.

CS->ST

: specifies that the curve starts at the curve to spiral and ends

at the spiral to tangent.

Right

Left

: specifies is the curve turns toward the right or left as you

face the spiral from the TS or CS.

Store SC

: When checked, saves a point for the computed SC

point.

Store PI

: When checked, saves a point for the computed spiral PI.

Results

Tangent In

: the tangent direction entering the spiral at the TS or CS.

Tangent Out

: the tangent direction exiting the spiral at the SC or ST.

X of Throw

: is the distance along the tangent where a perpendicular

line intersects with the radius point.
