To Create an Arc/Azimuth Survey Intersection

You can find the points of intersection between an arc and a line that is established by a point, azimuth, and offset.

To calculate the intersection of an arc and a line determined by an azimuth in the Survey Command Window

1. In Toolspace, on the Survey tab, right-click the network to edit, and click Survey Command Window.
2. Click Intersection menu Arc/Azimuth.
3. Enter the point number of the arc center.
4. Enter the radius of the arc.
5. Enter the starting point number of the line.
6. Enter the azimuth of the line.
7. Enter an offset.
8. Enter one of the following options:
   • N: To select the northern-most intersection.
   • S: To select the southern-most intersection.
   • E: To select the eastern-most intersection.
   • W: To select the western-most intersection.
   • R: To select the nearest intersection.
   • F: To select the farthest intersection.
   • 1: To select intersection 1.
   • 2: To select intersection 2.
   • A: To select all the intersections.
   • P: To pick the intersection with your pointing device.

To calculate the intersection of an arc and a line determined by an azimuth, using the survey command language

1. In Toolspace, on the Survey tab, right-click the network to edit, and click Survey Command Window.
2. At the Command line, enter:

   ARCAZ [point] [radius] [point 1] [azimuth] [offset]

Command Line Example

NE 1 100 100

NE 2 200 200

ARCAZ 2 200 1 50 50

! INTERSECTION # 1 NORTH:274.411634 EAST:385.641883

! INTERSECTION # 2 NORTH:30.099879 EAST:94.482471

Intersections are located between an arc radius of 200 with its center at point 2 and an azimuth of 50.0000 drawn from point 1 with an offset distance of 50 to the right.

Intersection of arc and line determined by azimuth

Command Syntax

ARCAZ [point] [radius] [point 1] [azimuth] [offset]

Parameter	Definition
point	The radial point. This is an existing point that is used as the center point for the arc.
radius	The radial distance in feet or meters for the first arc. Radial distance is the length of a line from the radius point to the arc.
point 1	The existing point from which a vector extends. It can be any type of point including a figure point.
azimuth	The azimuth of the line from the existing point. An azimuth establishes the direction for the vector and is expressed as current angle units.
offset	The distance to offset the intersection.
