To Create a Line/Line Survey Intersection

You can find the point of intersection between two lines defined from existing points. After an intersection is found, you can save it by specifying a new point number.

To create a Line/Line 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 Line/Line.
3. Enter the starting point identifier of the first line.
4. Enter the second point identifier to define the first line.
5. Enter an offset.
6. Enter the starting point identifier of the second line.
7. Enter the second point identifier to define the second line.
8. Enter an offset.

To create a Line/Line 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:

   LNLN [point 1] [point 2] [offset 1] [point 3] [point 4] [offset 2]

Command Line Example

NE 1 100 100

NE 2 200 200

NE 3 175 200

NE 4 100 200

LNLN 1 2 100 3 4 -100

! INTERSECTION # 1 NORTH:158.578644 EAST:300.000000

An intersection is located between a line drawn between points 1 and 2 with an offset of 100 feet to the right and a line drawn between points 3 and 4 with an offset of 100 feet to the left.

Command Syntax

LNLN [point 1] [point 2] [offset 1] [point 3] [point 4] [offset 2]

Parameter	Definition
point 1, point 2	The point identifiers that establish the position and direction of vector 1. Point 1 is the end point and Point 2 is the start point. These points can be any points including figure points.
offset 1, offset 2	The offsets from the lines. This acts as if the vectors 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 a zero for the offset.
point 3, point 4	The point numbers that establish the position and direction of vector 2. Point 3 is the end point and point 4 is the start point. These points can be any points including figure points.
