This command will stake out up to two user-defined horizontal offsets to a centerline at any station, as well as an unlimited number of offsets per station, if you are using a predefined Cutsheet Station and Offset List (loaded using the Settings button).  It will also stake out the centerline itself.  Station intervals can be entered, and the program will auto-detect, at the users option, special stations such as the TS, SC, PC, PT, CS, ST and vertical curve points (including high and low points).  Because individual stations and offsets can be entered, and also because pre-made station and offset lists can be recalled in the field, Offset Stakeout can be applied to virtually any offset point along a centerline.


Prerequisites and Procedures

Stake Offset requires both a horizontal and vertical alignment.  If total stations are involved, Stake Offset passes through the normal backsight confirmation screens that Store Points and other forms of Stakeout require. 


The Offset Stakeout command is a three-screen routine.  The first screen identifies and loads in the alignment files.  The second screen identifies the offset points to stake (slopes and distances) and the intervals or lists of stations/offsets to stake. The final screen goes to the standard graphics, shows the target points, and guides you to the destination, with N for Next continuing onto the next station in the interval or list.


Identifying the Alignments

The first screen has tabs for selecting both the horizontal and vertical alignments. See Stake Line/Arc for more detail.


Settings 

Use this button in the upper part of the screen to select predefined station lists and critical stopping points along the alignments.



Within this option, you can click the Stake tab and edit your default Stake Offset Descriptions shown below.  See Job Settings (Stake) for more details.



Entering the Offset Points as Slopes and Distances

The Offset Stakeout screen allows you to enter one or two offsets from the centerline.  The first offset requires a presentage slope and a distance. The second offset is for a curb or ditch, and is prompted in the form of “distance over” and “elevation change up or down”.






When using a Cutsheet Station and Offset list, you must select the List button, highlight the offset  you wish to use and press Select.  The routine will stay on this offset as it progresses through the stations until the user selects List again and specifies a new offset.


The Stake Offset command will store to the Alignment Stakes cutsheet file format if the file is named and made active for storing.  The data can include station and offsets as formatted.
