Exercise 1: Corridor Modeling – Getting Started Copying ITL File to “Working” Folder Copy TIP_rdy.itl (Blank Project File) from: C:\NCDOT_V8_WORKSPACE\ROADWAY_STDS\English\geopak\Corridor_Modeling\TIP_rdy.itl Into the following Directory: “C:\NCDOT Training\Roadway\CM\Chapter 1 – Intro to Corridor Modeling” *Actual Project Copy TIP_rdy.itl into R:\Roadway\CorridorModeling Rename TIP_rdy.itl by adding your TIP Project Number: Create & Open Corridor Modeling Design File Using “Design File Generator”, create a new 3D Corridor Modeling Design File. Name this file “b4834_rdy_cmd.dgn" (Saved in “CorridorModeling” folder). Open “b4834_rdy_cmd.dgn” file.
Attach Project Related Reference Under References (File / References) attach the following files: Start Corridor Modeling “Corridor Modeling” can be opened in the two following ways: Exercise 2: Setting Up Corridor Modeling Preferences Geopak Job Number Note: Before getting started, use Geopak COGO Preferences to update “Job (GPK) Directory:” Under Corridor Modeling Dialog, select next to . Choose project GPK file and select OK. Preferences
Copying Standard Templates with “Template Library Organizer…” Under “Create Template” select “Tools” then “Template Library Organizer…” Set Path to Access NCDOT_RDY_STANDARD Library (ITL) In right window of “Template Library Organizer” click on to set path for Master Template Library. Select and Drag Templates into “Project Specific Library (B4834_rdy.itl)”
Type in Name of Selection: L Click to Select Path of .INP File (Chapter 1 folder): Using Dropdown dialog, select Point: LT_PV1_OEOT Using Dropdown dialog, select Point: RT_PV1_OEOT Click on to add “Superelevation” to the Model. to Close “Import Superelevation from .INP file” Scan Through Templates to View Superelevation: Display References… Using “Display References…” to Check for Errors Listed below are Two Common Problems which “Display References…” could help the user to visualize: Default Template is designed to seek for “Proposed EOT” Plan Graphics from a default pavement width of 12’. If your project Plan
Graphics is shown using a 10’ proposed pavement width then the default template will not be able to find Plan Graphics (because it falls behind the 12’ point). Default Template is designed to use a 4’ “Proposed Paved Shoulder”. If your project Plan Graphics shows the Proposed Paved Shoulder of less than 4’ then the default template will not be able to find the Plan Graphics (because it falls behind the 4’ point). Using “Display References…” to Add “Left Side Proposed EOT” Plan Graphic “Display Reference” select Alignment drop down: Choose LT_Prop_EOT Select next to “Display as Right of Way” Under “Limits” select next to Station Next to type 13+20.00 Next to Stop: type 18+20.00 Click to add LT_Prop_EOT to list. After adding to list, a Purple Dashed Line will display in Cross Section View (representing the left Side Proposed EOT Line). Note: Repeat this process to add RT_Prop_EOT to list. How to Open Parametric Constraints By using the Tools Dropdown Menu:
How to Create Surface New Surface for Each Corridor. Empty Design Surface. Click Features. Components. Click on to create “Surface L”. Click to Close “Create Surface”. Save IRD File. Files Created during “Create Surface” Process The Create Surface Process creates the following (stored in the CorridorModeling Folder): L.DTM – Proposed 3D Model DTM L.TIN – Geopak Tin File Basic Rendering of 3D Model Use “View Display Mode” to View Basic Rendering of Model Turn off both Reference Files. “Fit View” to center Model. In Lower Left Corner of “View 1” click on “View Display Mode” scrolling up to select “Illustration”.
Select “Adjust View Brightness” and “Bar” to the Right to make Lighting Brighter. Under ”View Rotation”, Select “Rotate View”. Select and Hold Down “Left” Mouse Button (while moving mouse) to Rotate Model (in 3D).
