To Create a Bearing/Bearing Survey Intersection

You can find the point of intersection between two infinite lines from existing points.

After an intersection is found, you can save it by specifying a new point identifier.

To calculate a Bearing/Bearing intersection 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 Bearing/Bearing.
3. Enter the starting point number of the first bearing.
4. Enter the bearing from that point.
5. Enter the quadrant for the first point.
6. Enter an offset for the first points.
7. Enter the starting point number of the second bearing.
8. Enter the bearing from that point.
9. Enter the quadrant for the second point.
10. Enter the offset for the second point.

To calculate a Bearing/Bearing intersection, 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:

   BB [point 1] [bearing 1] [quadrant 1] [offset 1] [point 2] [bearing 2] [quadrant 2] [offset 2]

Command Line Example

NE 1 100 100

NE 2 200 200

BB 1 66.6667 1 50 2 33.3333 2 50

! INTERSECTION # 1 NORTH:100.000000 EAST:200.000000

An intersection is located between a bearing of N66.6667"E drawn from point 1, with an offset distance of 50 feet to the right and a bearing of S33.3333"E drawn from point 2 with, an offset distance of 50 to the right.

Command Syntax

BB [point 1] [bearing 1] [quadrant 1] [offset 1] [point 2] [bearing 2] [quadrant 2] [offset 2]

Parameter	Definition
point 1, point 2	The existing point identifiers that establish the beginning of the bearings.
bearing 1, bearing 2	The bearings for the lines from the existing points. Bearings establish a direction for each vector and are expressed in current angle units.
quadrant 1, quadrant 2	The quadrants in which the bearings exist. The possible values are: 1 (for NE), 2 (for SE), 3 (for SW), and 4 (for NW).
offset 1, offset 2	The offsets from the lines. This acts as if the lines are moved X feet or meters to the left or right. An offset to the right is a positive number, and an offset to the left is a negative number. If you do not want an offset, then use zero.
