Class Summary

In this class, we will discuss the required setup to automate survey functionality in Civil 3D, and how it can help reduce the amount of time needed to bring in points, automate linework graphics, and create surfaces. We will look at the critical importance of styles and settings. We will also examine some of the methods that can be used to create stakeout points for construction, and direct export for automatic machine guidance (AMG).

Linear Features (old way) There are methods that a surveyor can adopt that automate linework creation (e.g. EP, Tree line,

TBC, etc.) when the survey data is brought into Civil 3D

Linework Code Sets Civil 3D 2010 included additional functionality to automate linework creation Interprets field codes entered from surveyors into figures in the survey database Linework Code sets are displayed in the Toolspace under the Survey tab.

Civil 3D Setup

The linework code sets are stored in a separate file that has an F2f_Xdef extension.

Figures A figure is a linear object (breakline, parcel line, graphical line)

Figure Styles Figure style controls the display, layers, and 3D geometry of a figure Displayed under the Survey collection in the Settings tab.

Figure Prefix Database Figure prefixes are the means by which linework is connected to the appropriate figure style, layer,

and whether or not the figure should be a breakline or a parcel segment Similar to description keys Can also be set up in two different methods Stored in a Figure Prefix Database (FPD)

Line Coding Linework Code Set

Collecting Field Data

© 2011 Autodesk

Automatic linework can save time completing the final drawing Has been around since the old DCA days (pre-LDT)

Autodesk Fieldbook Language (.FBK) Field crews are the key to linework automation When survey is collected properly Civil 3D will automatically draw the survey data with little

manipulation from the office technician


Automation occurs because of specific line coding and field collection techniques that instruct the software to connect the dots automatically

Depending on the equipment, specific codes are entered before or after the raw code,

© 2011 Autodesk

Line Coding The command to begin drawing a line is B or BEG. You only need to use this code once per

figure. It is also important that you place a numeric identifier at the end of the figure name to make it unique (e.g. EP1, EP2, TOP1, TOP2)

To end the line, simply move on to the next figure number, or enter E or END at the end of the figure

Can also use the CONT command to continue a figure.


Some equipment have line work commands already programmed into them

© 2011 Autodesk

Line Coding (cont.) Additional line codes that can be used are listed in the table below

For a full list of available commands and their parameters, review the file cmdhelp.ref. This file is typically stored in the C:\ProgramData\Autodesk\C3D 2012\enu\Survey folder


Command DescriptionMCS Begins a curve with more than 3 points

MCE Ends a curve with more than 3 points

CB Closes and ends a figure adding a final vertex

CR Closes and ends a figure adding 2 vertices

© 2011 Autodesk

Line Coding (cont.) Some examples of codes are listed below

TBC1 BEG TBC1 CONT EP3 BEG CL1 BEG C3

<three consecutive points for the curve (PC, POC, PT)> CL1 CONT CL1 END

Again, verify how data is entered into your equipment. You may want to test a small project to determine exactly how your equipment translates the field data into drawing data


© 2011 Autodesk

Linework Code Set Provides very powerful ways to create linework with minimal input from the survey upon collection

time Example…

TBC H.5 V0 H.67 V-.5 H2.0 V-.47 H-5 V.02 H and V codes tell Civil 3D to create additional lines based on the horizontal and vertical offsets

defined in the description.

Civil 3D Setup

In Civil 3D Survey Toolspace, additional figures appear as <description>.n, where n is equal to the number offset.

Creating a Surface from Survey Data

© 2011 Autodesk

Surface creation can be automated and take minutes when Civil 3D is setup properly The following procedure is used to create a surface from survey data:

1. Insert the survey points into the drawing from the survey database.2. Create a point group that will only contain the existing points that should be used for surface

creation.3. Create an existing surface with the appropriate surface style associated to it.4. In the Surfaces definition node, right-click on the Point Group category, and then add the

point group created in step 2.5. Right-click on the Figures collection in the Survey Toolspace, and then choose Create

Breaklines from the context menu that appears. Toggle the breaklines you want to add to the existing surface on or off.

6. Add an outer boundary to the surface.

(NOTE: Only breaklines that are toggled on will be available to be added to the surface)
