To Create a New Point by Station, Offset, and Vertical Distance

You can create a point given a vertical distance, with respect to the current centerline, height of instrument, and prism height.

The elevation is computed by subtracting the prism height from the instrument height, then algebraically adding the vertical distance.

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

To create a point along a centerline using a vertical distance from the Survey Command Window

1. In Toolspace, on the Survey tab, right-click the network to edit, and click Survey Command Window.
2. Click Centerline menu Station/Offset Vertical Distance.
3. Enter the point number of the point you want to create.
   Note: If auto point numbering is on, then the next point is displayed.
4. Enter the station of the new point. The station can be a positive or a negative value.
5. Enter the offset of the new point. The offset can be a positive or a negative value.
6. Enter the vertical distance.
7. Optionally, enter a description for the point.

To create a point along a centerline using a vertical distance, 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:

   CL VD (point) [station] [offset] [vertical distance]
