To Create a Point Along a Survey Centerline by Station, Offset, and Rod Height

You can create a point by specifying a station, offset, and rod height from the current centerline. The elevation is computed by algebraically adding the rod reading to the current value set with the Set Height of Instrument command.

To create a point along a centerline using a rod reading 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 Rod.
3. Enter the station.
4. Enter the offset.
5. Enter the rod reading.
6. Optionally, enter a description for the point.

Command Syntax

CL ROD (point) [station] [offset] [rod] (description)

Parameter	Definition
point	The point identifier for the new point. You do not need to assign a point number if auto point numbering is on.
station	The station of the new point.
offset	The perpendicular distance from the centerline 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.
