Exercise 1: Viewing Inverse and Mapcheck Information on a Survey Figure
In this exercise, you will display the figure mapcheck and inverse information.
Tutorial: Outputting Survey Information | 171
The Mapcheck command checks the figure for length, course, perimeter, area, error of closure, and precision. It starts at the beginning of the figure and computes the figure vertex XY coordinates for each segment. These
computations are based on the inverse direction and distance/curve data and the Linear and Angle precision (set in the Survey Database Settings).
For closed figures, error is introduced into the sequential computation of vertices of the mapcheck report, so a closure error, closure direction, and precision can be calculated. The area is also based on the computed vertex XY coordinates.
The Inverse command starts at the beginning of the figure and lists the direction and distance, or curve data computed from the XY coordinates of the endpoints of the figure segments. The area is calculated from the XY coordinates of each segment.
For more information, see the AutoCAD Civil 3D Help topic Figure Inquiry Commands.
This exercise continues from the Manually Creating Survey Data (page 155) tutorial.

To continue this tutorial, go to Exercise 2: Performing a Mapcheck Analysis with Parcel Labels (page 173).
Exercise 2: Performing a Mapcheck Analysis with Parcel Labels
In this exercise, you will use the data in parcel segment labels to perform a mapcheck analysis.
The Mapcheck command checks the figure for length, course, perimeter, area, error of closure, and precision. It starts at the beginning of the figure and computes the figure vertex XY coordinates for each segment. These computations are based on the actual labeled values, and not the inverse direction and distance/curve data and the Linear and Angle precision (set in the Survey Database Settings).
This method of performing a mapcheck analysis is useful as a final check of closure. The data for the mapcheck analysis is taken from parcel segment labels. The precision of the mapcheck analysis is based on the precision of the labels.
For more information, see the AutoCAD Civil 3D Help topic Performing a Mapcheck Analysis.
This exercise continues from Exercise 1: Viewing Inverse and Mapcheck Information on a Survey Figure (page 171).
Set up the mapcheck analysis dialog box
1 Open Survey-5B.dwg, which is located in the tutorial drawings folder (page 819).
This drawing contains a small subdivision with several parcels. All the parcel segments on the left side of the site are labeled. Notice that along the cul-de-sac, the line and curve labels have been converted to tags, and their data is displayed in a table on the left side of the site. You will perform a mapcheck analysis on parcel LOT 5.

2 Click Analyze tab ➤ Ground Data panel ➤ Survey drop-down ➤ Mapcheck .
3 If a message that states that the command line mode cannot be used while a command is active is displayed, click OK.
4 In the Mapcheck Analysis dialog box, make sure that the Use Command Line Interface option is toggled on.
5 Click Input View.
The input view provides an interface in which you can add data to the mapcheck analysis.
Perform a mapcheck on parcel labels
1 Click New Mapcheck.
2 On the command line, for the name of the mapcheck, enter Parcel Labels.
3 When prompted to specify a point of beginning, click the intersection of the lot lines under label tag L1.
The icon indicates the point of beginning.
4 Select the L1 label tag above the point of beginning.
A temporary arrow graphic is displayed at the point of beginning. Notice that the arrow is pointing away from LOT 5.
5 On the command line, enter R to reverse the direction of the arrow.
6 Select the C1 label tag.
Notice that the temporary line and arrow are pointing in the wrong direction.
7 Enter F to flip the arrow.
8 Select the C2 label tag.
9 Select the bearing over distance label to the left of the arrow. Enter R to reverse the direction.
10 Select the 100.00’ portion of the bearing over distance label below the arrow.
A icon appears at the end of the current line, and the command line states that there is not enough data to define the segment. This happened because the current segment is a lot line that is shared by all the parcels on the left side of the site.
11 Select the bearing portion of the label. Enter R to reverse the direction.
12 Select the bearing over distance label to the right of the arrow.
The arrow returns to the point of beginning.

In this exercise, you will use figures to add breaklines to a surface.
The breaklines will define the edge of pavement (EP) features, such as retaining walls, curbs, tops of ridges, and streams. Breaklines force surface triangulation along the breakline and prevent triangulation across the breakline.
For more information, see the AutoCAD Civil 3D Help topic Creating Breaklines from Figures.
