Skew Angle of 20 degrees, as measured forward from the perpendicular (normal) offset.
Elevation:
This is the design elevation. If the defined geometry is 2D, then this option will be active.
Override Design:
This allows the user to override the design elevation of 3D geometry.
Off. Inc
: This is for entering an optional incremental offset along the line. This is a rarely used feature that would
trend the offsets away or in to the centerline.
Segment:
This defines the current segment of the alignment based on the entered station.
Cutsheet:
This shows the currently selected Alignment Cutsheet file.
Settings:
This icon takes you to the Job Settings that apply to alignment staking. See Job Settings (Stake) for
more details. Note that this is where you instruct the software to include and stop at critical alignment locations.
Stake Line/Arc (Point On Line)
The Point On Line option appears when Define Line or Define Alignments is selected with Stake Station Interval
clicked on. The options appear in the Stake Line (Interval) dialog. It offers a Perpendicular to Line method for total
stations and GPS. This method projects any shot onto the alignment perpendicular or radial in curves, and prompts for
the distance and direction to move to the alignment intersect point. However, only if you select Define Line as the
method to define the alignment and you are set to total stations, is there a "Find Intersect to Line" option, which enables
“line-of-sight” staking of lines. This is often used by surveyors who are setting line in tree lines, moving to gaps in the
trees for readings, then moving in-out along the line-of-sight and driving stakes when perfectly on line. It is useful for
any line or boundary staking, such as property lines, right-of-ways and construction lines. For GPS, only the
Perpendicular method is available.
Total Stations: The Offset to Line option is grayed out when the Find Intersect to Line method is selected and
available only when the Perpendicular option is chosen.
Total Stations, Define Line, Point On Line, Intersect to Line:
The Intersect Method is used to set line by moving in
or out at the current line of sight. A major application is setting line where the line is largely blocked by trees or
obstructions, and you must set the line in gaps where you do have a line of sight.
