You can calculate the intersection(s) of a line established by two points, and an arc established by a radial point and radius.
To calculate an Arc/Line intersection in the Survey Command Window
- In Toolspace, on the Survey tab, right-click the network to edit, and click Survey Command Window.
- Click Intersections menu
Arc/Line. - Enter the point identifier of the arc center.
- Enter the radius of the arc.
- Enter the starting point identifier of the line.
- Enter the ahead or the direction point for the line.
- Enter an offset.
- 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 an Arc/Line intersection, using the survey command language
- In Toolspace, on the Survey tab, right-click the network to edit, and click Survey Command Window.
- At the Command line, enter:
ARCLN [point] [radius] [point 1] [point 2] [offset]
Command Line Example
NE 1 100 100
NE 2 200 200
NE 3 250 100
ARCLN 3 200 1 2 -100
! INTERSECTION # 1 NORTH:387.066972 EAST:245.645615
! INTERSECTION # 2 NORTH:104.354385 EAST:-37.066972
Intersections are located between an arc radius of 200 with the center at Point 3 and a line drawn between Points 1 and 2 with an offset distance of 100 to the left.

Command Syntax
ARCLN [point] [radius] [point 1] [point 2] [offset]
| Parameter | Definition |
|---|---|
| point | The point number of the radial (center) point. |
| radius | The radial distance in feet or meters. The radial distance is the length of a line from the radius point to the arc. |
| point 1, point 2 | The existing points that establish the position and direction of the line. Point 1 is the start point and point 2 is the end point. These points can be any points including figure points. |
| offset | The offset from the vector. This acts as if the line is moved a specified number of 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 any offset, then use zero. |
