To Create a Point on a Survey Cross Section by Offset and Rod Height

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

  1. In Toolspace, on the Survey tab, right-click on the network to edit, and click Survey Command Window.
  2. Click Centerline menu Offset Rod.
  3. Enter the point number of the point you want to set.
  4. Enter the offset of the new point. The offset can be a positive or a negative value.
  5. Enter the rod height.

To create a point by offset and rod height from the current cross section, using the survey command language

  1. In Toolspace, on the Survey tab, right-click on the network to edit, and click Survey Command Window.
  2. At the Command line, enter:

    XS ROD (point) [offset] [rod] (description)

Command Line Example

BEGIN CL1

NE 1 1000 1000

NE 2 1000 1500

NE 3 1300 1700

END

CL IS CL1

XS 350

HI 200

XS ROD 100 150 7.25

! POINT 100 NORTH: 850.000 EAST: 1350.000 ELEV: 192.750

Point 100 is offset from cross section 350 a distance of 150 with an elevation of 192.75 (height of instrument - rod).

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.
