The Stake Out Point (Store/Tape) screen allows you to store a point at a specified offset from the stake point, resulting
in a point that is either closer to, or further away from the total station.

Point: is the name assigned to the new offset point.

Description: is the description assigned to the new offset point.

Tape Out/Tape In: is the specified offset from the stake point. A positive value will result in a new point that is
further away from the total station. The default value is the appropriate distance correction to the design point.

: stores the new offset point.

Stake Spiral and Offset

[Stakeout] [Spiral and Offset]

The Stake Spiral and Offset screen allows you to stake stations at fixed intervals on a spiral curve, or at an offset to
it.

Start Point: is the point associated with the 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).

Stake Spiral and Offset - Screen 2

Station to Stake: is the desired station on the spiral curve that you want to stake.

Station Interval: is the value that is added to the Station to Stake after the [Next Sta] button is pressed.

[Next Sta]: advances the Station to Stake by the Station Interval.

Offset: is the horizontal distance of the offset from the spiral curve. The offset occurs on the left (while viewing the
spiral from the Start Point) when the L is selected or on the right when R is selected.

Note: An offset of zero would result in the spiral curve itself being staked.

[V. Offset]: will result in the elevations for the design points to be adjusted by the value entered here and will change
