To Create a Square Offset Intersection

You can determine the offset, distance, and point of intersection where a right angle would be projected onto an infinite line (defined by two points). After an intersection is found, you can save it by specifying a new point identifier.

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

To create a square offset 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 Square Offset.
3. Enter the starting point identifier of the line.
4. Enter the second point identifier to define the line.
5. Enter the point identifier of the point offset from the line.

   AutoCAD Civil 3D determines the offset distance of the point (entered in step 5) from the line established by the first two points. This establishes one known side distance and two known side directions. Using this information, AutoCAD Civil 3D calculates the corners of a square and creates the corner of the square offset from the line (established in steps 3 and 4) at the same distance as defined by the point entered in step 5.

To create a square offset, 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:

   SQ [reference 1] [reference 2] [reference]

   

Command Line Examples

The following example shows a valid entry using the Square Offset command:

SQ 302 303 501

This example finds the point that creates a right angle between the line from point 302 to point 303 and point 501.

SQ 13 14 501

This example finds the point that creates a right angle between the line from point 13 to point 14 and point 501.

The Square Offset command lists the ahead distance and offset distance to the point of intersection.
