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

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

To create a point along a centerline using a pole 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 Chainage/Offset Pole.
3. Enter the station.
4. Enter the offset.
5. Enter the pole reading.
6. Optionally, enter a description for the point.

To create a point along a centerline using a pole reading, using the survey command language

Command Syntax

CL POLE (point) [station] [offset] [pole] (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.
pole	The pole height. This value is subtracted from the height of instrument level to determine the level of the new point.
description	An optional description associated with the point.
