Traverse

This command allows the user to input any combination of turned angles, azimuths or bearings to define a traverse or figure. The command prompts for an Angle-Bearing Code which defines the angle or bearing type. This command always occupies the last point it calculated and backsights the point before that.

Codes 1 through 4 define the bearing quadrants:
1 = Northeast
2 = Southeast
3 = Southwest
4 = Northwest

The remaining codes define as follows:
5 = Azimuth
6 = Angle turned to the left
7 = Angle turned to the right
8 = Deflection angle left
9 = Deflection angle right

For both the Angle-Bearing Code and the Distance prompt, the user can enter point-defined responses: two points separated by an asterisk, as in 2*3 for the bearing (or distance) defined by 2 to 3. You can also add math expressions. For angles, 2*3+90 would deflect 90 degrees right from 2 to 3. For distances, 2*3/2 would mean half the distance of 2 to 3. You do not need to enter N before entering a number-defined distance. Just bring up the number inverse prompt. For distances, the # symbol can also be used to indicate point numbers like in SurvCE. So 2#3 means the distance between points 2 and 3.

The command draws lines between located points (if the Line On/Off in the COGO menu is set to on) and plots the points calculated and stores them in the current coordinate (.CRD) file if point numbering is On. The point settings are defined in the Point Defaults command. If Point Protect is turned on, Traverse checks if the point numbers are already stored in the file. Point Protect is set in the Coordinate File Utilities command.

There are Angle-Bearing code input options for Traverse that are set by entering O for Options. The Angle Right option prompts for the angle right and skips the angle-bearing code prompt. The Azimuth option prompts for the azimuth and skips the angle-bearing code prompt.

Prompts

Occupied Point ?
Pick point or point number: pick a point
You will only be prompted for the occupied point the first time you use the command.
Use the Inverse command to set the occupied and backsight points.
Exit/Options/SideShot/Inverse/Enter Azimuth (ddd.mmss) <>: o
Angle prompt angle right or azimuth only [Right/Azimuth/Prompt]? p
Exit/Options/Arc/Points/Line/SideShot/Inverse/Angle-Bearing Code <5>: press Enter Pressing Enter uses the default angle right code.
Enter Angle (dd.mmss) <90.0000>: 88.1324 You can also enter L or R to define an angle 90 degrees Left or Right.
Backsight Point ?
Pick point or point number: pick a point
Number inverse/<Distance>: 100

Select Coordinate (.CRD) File This dialog only appears if there is not a current coordinate (.CRD) file.
Exit/Options/Line/Side Shot/Inverse/<Angle-Bearing Code <7>>: 14*9-45.2045 Uses the bearing defined by point numbers 14 & 9 and subtracts the angle 45 degrees, 20 minutes, and 45 seconds. You can use a + or - in this type of entry.
Number inverse/<Distance>: N (note: you can enter 14*9/2 here, as well)
Point number inverse (i.e. 10*20): 14*9/2 This causes the command to recall the distance from point number 14 to 9 and divide it by 2.
Exit/Options/Line/Side Shot/Inverse/<Angle-Bearing Code <7>>: L
Select Line or Polyline that defines Bearing: select line that defines bearing
Number inverse/<Distance>: 100
Exit/Options/Line/Side Shot/Inverse/<Angle-Bearing Code <7>>: E Enter E to end the command. Enter S or SS to execute the Side Shots command or I to execute the Inverse command.
