Using the network least squares adjustment method.
Each method produces slightly different results. The standard compass rule
adjustment method adjusts the traverse loop and sideshots. The least squares
method adjusts each of the observations so that the sum of the residuals is at
a minimum.
NOTE
Before performing the steps in this tutorial, you must have already created
the survey database Survey 1 and imported the field book file
Survey-1.fbk
. For
more information, see the
Survey Setup
(page 129) and
Importing and Viewing
Survey Data
(page 144) tutorials.
For more information, see the AutoCAD Civil 3D Help topic Survey Analysis
and Output.
Exercise 1: Querying Survey Data
In this exercise, you will use the Survey Command Window to perform a
query on the survey data.
You will use the Inverse Points command to determine the direction and
distance between two points.
For more information, see the AutoCAD Civil 3D Help topic Survey Command
Window.
This exercise continues from the
Importing and Viewing Survey Data
(page
144) tutorial.
Specify the survey database settings
1
Open Survey-3.dwg, which is located in the
tutorial drawings folder
(page
819)
This drawing contains the survey network that was created in the
Importing Field-Coded Survey Data
(page 136) exercise.
2
In Toolspace, on the Survey tab, expand the Survey Databases collection.
3
If the database Survey 1 is not open (that is, it is not displayed with a
next to it), right-click and click Open For Edit.
NOTE
By default, to save on resource usage, when you start AutoCAD Civil
3D, all survey databases are displayed in a closed state.
