Corridor Modeling Seed File
Using “Design File Generator”, create a new 3D Corridor Modeling Design File (naming example: "B1000_rdy_cmd.dgn").
What is an ITL File?
This file is the collection of templates (or typical sections) used to define
the proposed roadway. This is where Components, Templates and End Conditions
are created, edited and stored.
We will be using two types of ITL Files:
| Master
Template Library: |
NCDOT Standardized Master Template Library |
| |
|
| Project
Template Library: |
Project specific Template Library.
Templates will be taken from |
| |
"Master Template Library" and copied into
the "Project Template |
| |
Library". |
| |
Note: When starting a new Project,
this file will need to be copied |
| |
from the ROADWAY_STDS Workspace into the |
| |
"CorridorModeling" folder. |

1) Copying ITL file into "CorridorModeling"
folder
- Locate the following directory:

- From this directory, copy the TIP_rdy.itl file into the "CorridorModeling" folder.

- Rename TIPXXXX.itl by adding your TIP Project Number.

2.) Open Corridor Modeling Design File /
Attach Reference Files
- Open Corridor Modeling Design File (Example: "b1000_rdy_cmd.dgn")
- Attach Reference Files (Example: "b1000_rdy_eop.dgn, b1000_rdy_dsn.dgn)
3.) Set "Job (GPK)" Directory under Geopak "User
Preferences"
- Under "Applications" select: ROAD / User Preferences
- Under "User Preferences" select: COGO Preferences
- Under "Job (GPK) Directory" choose path for Project GPK Folder

4.) Opening Corridor Modeling
- Corridor Modeling can be opened in the two following ways:
