You can create a point by specifying a vertical distance from the current cross section, height of instrument, prism height, and centerline.
The elevation is computed by subtracting the prism height from the value you specified with the Set Height Of Instrument command, and then adding the vertical distance.
To create a point by offset and vertical distance 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 Vertical Distance. - Enter the point number of the point you want to create.
- Enter the offset of the new point. The offset can be a positive or a negative value.
- Enter the vertical distance.
To create a point by offset and vertical distance 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 VD (point) (offset) [vertical distance]

Command Syntax
XS VD (point) (offset) [vertical distance]
| 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 centerline to the new point. A positive distance indicates an offset to the right, and a negative distance indicates an offset to the left. |
| vertical distance | The elevation difference from the instrument to the prism. If the prism is higher than the instrument, then this is a positive value. |
