Exercise 4: Translating a Survey Database
In this exercise, you will translate the contents of a survey database from
assumed coordinates to that of known coordinates.
This command is useful when you must move all the data in the survey
database from an assumed location to a known location.
For more information, see the AutoCAD Civil 3D Help topic Translating a
Survey Database.
This exercise continues from
Exercise 3: Performing Least Squares Analysis
(page 152).
Examine the contents of a survey database
NOTE
This exercise uses

Click the Setups collection.
In the list view, examine the elevation values of the following setups:
■
Station Point 1, Backsight Point 1000: Instrument Elevation = 263.650
■
Station Point 2, Backsight Point 1: Instrument Elevation = 259.960
■
Station Point 3, Backsight Point 2: Instrument Elevation = 257.438
For this exercise, you will assume that the elevation value for Station
Point 1, Backsight Point 1000, which is at Easting 5000 and Northing
5000, is 2.25 greater than the actual elevation.
