To Create an Arc/Arc Intersection

You can calculate the intersection(s) of two arcs, each defined by an existing center point and a radius.

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

To calculate the intersection of two arcs 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 Intersections menu Arc/Arc.
3. Enter the point identifier of the first arc center.
4. Enter the radius of the first arc.
5. Enter the point identifier of the second arc center.
6. Enter the radius of the second arc.
7. 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 two arcs, 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:

   ARCARC [point 1] [radius 1] [point 2] [radius 2]

Command Line Example

NE 1 100 100

NE 2 200 200

ARCARC 1 100 2 200

! INTERSECTION # 1 NORTH:8.856217 EAST:141.143783

! INTERSECTION # 2 NORTH:141.143783 EAST:8.856217

Intersections are located between an arc radius of 100 with a center at Point 1 and an arc radius of 200 with its center at Point 2.
