The Stake Spiral and Offset screen allows you to stake stations at

fixed intervals on a spiral curve, or at an offset to it.

beginning of the spiral curve. This can either

be the TS or the CS, which is specified later in

this screen (see below).

Tangent Azm | Tangent Bearing : defines the

tangent azimuth or bearing at the entrance to

the spiral

Radius | Degree Arc | Degree Chord :

defines the radius, degree arc, or degree chord

of the curve, respectively.

Length: is the length of the spiral curve.

Begin Station: is the station associated with the Start Point.

Turn: defines if the curve turns toward the Left or Right from the

point of view of the Start Point.

Spiral: defines the direction of the spiral curve by the following

options:

• TS to SC: the spiral begins at the tangent (Tangent to Spiral)

and ends at the circular curve (Spiral to Curve).

• CS to ST: the spiral begins at the circular curve (Curve to

Spiral) and ends at the tangent (Spiral to Tangent).
