You can create a point by giving an offset and rod height with respect to the current cross section, height of instrument, and centerline.
The elevation is computed by subtracting the rod from the current value you set with the Set Height of Instrument command.
To create a point by offset and rod height from the current cross section in the Survey Command Window
- In Toolspace, on the Survey tab, right-click on the network to edit, and click Survey Command Window.
- Click Centerline menu
Offset Rod. - Enter the point number of the point you want to set.
- Enter the offset of the new point. The offset can be a positive or a negative value.
- Enter the rod height.
To create a point by offset and rod height from the current cross section, using the survey command language
- In Toolspace, on the Survey tab, right-click on the network to edit, and click Survey Command Window.
- At the Command line, enter:
XS ROD (point) [offset] [rod] (description)

Command Syntax
XS ROD (point) [offset] [rod] (description)
| Parameter | Definition |
|---|---|
| point | The identifier of the new point that you want to create. You do not need to assign a point number if auto point numbering is on. |
| offset | The distance from the cross section to the new point. |
| rod | The rod height. This value is subtracted from the height of instrument elevation to determine the elevation of the new point. |
| description | An optional description associated with the point. If you use a description key, then specific information is assigned to the point. |
