You can use the Inverse Radial command to determine the angle and distance from a setup in a radial direction from the backsight point. You must specify a backsight point identifier, an instrument point identifier, and a foresight point.
To list angle and distance information using the Survey Command Window
- In Toolspace, on the Survey tab, right-click a named network
Survey Command Window. - In the Survey Command Window, click Point Information menu Inverse Radial.
- Enter the point identifier of the backsight.
- Enter the point identifier of the instrument point.
To list angle and distance information using the Command line in the Survey Command Window
- In Toolspace, on the Survey tab, right-click a named network Survey Command Window.
- At the command line, enter:
INVERSE RADIAL [backsight] [station]
Command Line Example
The following example shows a valid entry using the Inverse Radial command:
NE 1 100 100
NE 2 200 200
NE 3 175 300
NE 4 300 200
NE 5 310 220
NE 6 200 250
INVERSE RADIAL 2 1
Inverses reference instrument at point 2 backsighting point 1 3
Angle: 24-26-38 Distance: 213.600
POINT 3 NORTH: 175.000 EAST: 300.000 ELEV: <Null> 4 6
Angle: 341-33-54 Distance: 223.610
POINT 4 NORTH: 300.000 EAST: 200.000 ELEV: <Null>
Angle: 344-44-42 Distance: 241.870
POINT 5 NORTH: 310.000 EAST: 220.000 ELEV: <Null>
Angle: 11-18-36 Distance: 180.280
POINT 6 NORTH: 200.000 EAST: 250.000 ELEV: <Null>
The instrument is set on point 2, backsights point 1, and gives the angle turned from line 2-1 to line 2-3. This command returns the distance from point 2 to point 3, then does the same for points 4 through 6.
