To Create an Arc/Bearing Intersection

You can calculate the intersection between a line and an arc. The line is established by a point, quadrant bearing, and offset.

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

To calculate the intersection of an arc and quadrant bearing line 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/Quadrant Bearing.
3. Enter the point identifier of the arc center.
4. Enter the radius of the arc.
5. Enter the starting point identifier of the line.
6. Enter the quadrant bearing of the line.
7. Enter the quadrant of the line.
8. Enter an offset.
9. 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 solution nearest.
   • F: To select the solution farthest.
   • 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 quadrant bearing line, 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:

   ARCB [point] [radius] [point 1] [quadrant bearing] [quadrant] [offset]

Command Line Example

NE 1 100 100

NE 2 200 200

ARCB 2 200 1 50 1 -50

! INTERSECTION # 1 NORTH:372.285978 EAST:301.575300

! INTERSECTION # 2 NORTH:98.424700 EAST:27.714022

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