To Create an Observation by Angle and Distance

Use the angle distance (AD) command to quickly create a point by angle and distance.

Create a point using an angle turned from either a specified reference line or a previously determined backsight point. You can also use a vertical angle or vertical distance to locate the point.

Note: For parameter descriptions, see the Quick Reference tab.

To create an observation by angle and distance, using the command language

1. In Toolspace, on the Survey tab, right-click the network that you want to add points to, and click Survey Command Window.
2. At the Command line, enter:

   AD (point) [angle] [distance] (description)

To create an observation by angle, distance, and vertical angle, using the command language

1. In Toolspace, on the Survey tab, right-click the network that you want to add points to, and click Survey Command Window.
2. At the Command line, enter:

   AD VA (point) [angle] [distance] [vertical angle] (description)

To create an observation by angle, distance, and vertical distance, using the command language

2. At the Command line, enter:

   AD VD (point) [angle] [distance] [vertical distance] (description)

Examples

This example creates point 103, which is located by turning a horizontal angle of 80°20'40" right at a distance of 100 units from the instrument point with the description WELL. Because no method of vertical difference determination was given, the elevation is <Null>.

AD 103 80.2040 100 WELL

This example creates point 101, which is located by turning a horizontal angle of 100°20'45" right from the backsight and using a vertical angle of 91°15'15" at a distance of 100 units from the instrument point with the description IP.

AD VA 101 100.2045 100 91.1515 IP

This example creates point 102, which is located by turning a horizontal angle of 90°30'30" right from the backsight and using a vertical distance of -1.5 units at a distance of 200 units from the instrument point with the description EL.

AD VD 102 90.3030 200 -1.5 EL

Points created with the angle distance command:

Point 101 is located by turning a horizontal angle of 100°20'45" right from the backsight and using a vertical angle of 91°15'15" at a distance of 100 units from the instrument point with the description IP.

Point 102 is located by turning a horizontal angle of 90°30'30" right from the backsight and using a vertical distance of -1.5 units at a distance of 200 units from the instrument point with the description EL.

Point 103 is located by turning a horizontal angle of 80°20'40" right at a distance of 100 units from the instrument point with the description WELL. Because no method of vertical difference determination was given, the elevation is <Null>.
