Check TOPORD Levels
Several Survey related levels changed recently.
Make sure the elements in your TOPORD file
have been updated before copying elements
into the GKLNRD file.

Elements on invalid levels will be copied
onto the Default level when copied into a file
from a reference

Open the TOPORD file (or a copy of it)

Select Actions > Quality Control > QC
Legacy from the FDOT menu
QC Legacy
QC Legacy scans the file for
elements on legacy levels and
then allows you to fix them by
selecting a currently valid level.

QCInspector Interface

Sort by Column Headers

Windows Selection Methods

Right-click to Fix
Create a New GDTMRD File
If the survey data for you project contains a TIN file and
a GDTMRD file with a mesh element you will need to
create another file for the new Terrain element.

Launch the FDOT Create File application.
 Select the desired project
 Choose the Roadway.CTL Control File
 Choose the “Survey Design File (DGN)” File Group
 Select the File Type “Digital Terrain Model / TIN Model – 3D”
 Click the Create button
 Click the Open button
Set the Geographic Coordinate System
Set the Geographic Coordinate System
file in the new GDTMRD file.

Select Actions > Set Geographic
Coordinate System from the FDOT
menu
 Click on the county where the
project is located
Import Existing Terrain

From the Task Menu select “Civil Tools > Terrain
Model > Create From File”

When prompted browse to and select the TIN file

After selecting the TIN file the Import Terrain Model(s)
dialog will appear

Set the Units to US
Survey Foot and
select the
appropriate
Feature Definition
then Click Import
Create a GKLNRD File
The GKLNRD file will store the existing features model.

Launch the FDOT Create File application.
 Select the desired project
 Choose the Roadway.CTL Control File
 Choose the “Roadway Design File (DGN)” File Group
 Select the File Type “GEOPAK Lines for Existing Features”
 Click the Create button
 Click the Open button
Set the Geographic Coordinate System
Set the Geographic Coordinate System
file in the new GDTMRD file.

Select Actions > Set Geographic
Coordinate System from the FDOT
menu
 Click on the county where the
project is located
Existing Features Task Menu
The Existing Features task menu contains tools frequently
used during the creation of Existing Features models.

The Q row contains tools for creating the shapes

The W row contains terrain tools

The E row contains tools for linear templates and cross
section viewing

The Main Task contains most frequently used tools in all
workflows
FDOT’s Existing Features Application
After opening the GKLNRD file set the Geographic
Coordinate System and then run the Create Existing
Features app.

On the Task menu select the “FDOT Plans Development
Workflow > Existing Features > Create Existing Features”

When Prompted browse to and select the TOPORD file
 Once selected the TOPORD file is referenced and the
levels typically used to create existing features are
copied into the GKLNRD file.
- The display of the referenced TOPORD is turned off
Creating Shapes With the Existing Features Application
The FDOT Features app will manage the active level
and the display of levels
1.
Choose Feature
2.
Close areas of shape using place line command
3.
Use Flood Tool (Middle Icon) to create complex
shape elements for each existing feature area.
Attach References

Attach the following references:
 GDTMRD
 RWDTRD
 Set the terrain in the GDTMRD file
to active.
Clipping Terrains
The shapes created in the previous steps will be used to
clip areas from the existing ground terrain in the GDTMRD

Use the FDOT Features app to manage levels

Select the Clip Terrain tool from the Existing Features
task menu.
 Set Clipping Method to External
 Set Feature Definition to
“DtmExistingFeature”
 Set Name to represent area
 Follow prompts on cursor
Surface Templates
Surface Templates can be applied to each terrain to
define depth and symbology.
Apply Surface Template

Click on the Apply Surface Template icon

Select the Template to be applied

Click on terrain boundary of the existing feature

Follow cursor prompts
Edit an Applied Surface Template
There are a couple ways to edit a Surface Template
after it has bee applied:

Click “Edit An Applied Surface Template” on the
Existing Features task menu

In Project Explorer, right-click on the Surface
Template listed under the Terrain Model
Curb and Gutter
Existing Features like curb and gutter do not have a constant thickness so
surface templates will not work. A Linear Template will be used to define the
subsurface lines of the curb and gutter.
1.
Create a chain of the back of curb if necessary
 Task Menu > Civil Tools > Horizontal Geometry > Complex by Element
2.
Open Profile view for back of curb and set the existing ground as the “Active” profile
3.
Apply linear template to back of curb line in plan view
4.
Set the “Feature” for the existing edge of pavement to “Pavement Existing”
5.
Add the existing edge of pavement as a “Corridor Reference”
1. Complex by Element
This step is only needed if the existing back of curb line is
broken into several pieces.

On the Task menu select “Civil Tools > Horizontal
Geometry > Complex by Element”

Set the Feature to “CurbExisting”

Follow prompts on cursor
2. Open Profile View for Back of Curb

Select the back of curb element then hover
over it to get the context menu
 Select “Open Profile Model” from the
context menu and then select the view to
open the profile in

Select the profile then hover over it to get the
context menu
 Select “Set as Active
Profile”
3. Apply Linear Template

Select ”Apply Linear Template”

Click the Browse button to choose a template

Follow prompts on cursor
4. Set Feature for Existing EOP
The Linear Template is using a Horizontal Feature
Constraint to search for an element with a Feature
Definition of “PavementExisting”.

Select ”Set Feature Definition”

Choose the Feature Definition “PavementExisting”

Follow prompts on the cursor
5. Add Corridor Reference

Select ”Add Corridor Reference” from the
Existing Features task menu

Follow prompts on the cursor
Viewing Cross Sections
To view the Cross Sections you will be prompted for an
alignment or a corridor. Import the alignment into the file.

On the Task menu select “Civil Tools > General
Geometry > Import Geometry”

When prompted, select
the GPK file

Select the alignment and
click Import
Viewing Cross Sections

Select ”Open Cross Sections in a View” from the
Existing Features task menu

Follow prompts on the cursor
 When prompted for Left Offset click on the left
side of the baseline to accept.
 When prompted for Right Offset click on the right
side of the baseline to accept.
FDOT.Features.XML
FDOT.Features.XML controls the levels turned on and off as different features
are selected from the dropdown. A couple of adjustments have been made to
this files since FDOTSS4 was released. An updated version of the file is
