Apply Linear Templates

This module instructs users how to place a linear template in a design file for a project. When placing linear templates, a corridor is not needed, linear templates can be applied to 3D elements.

1. Load Corridor (Roadway Model) file and Load the Template Library for the project. See Section 3 - The Template Library for loading or creating Templates.

2. Activate the OpenRoads Modeling workflow from the pick list next to Quick access toolbar in the upper left corner if it is not already active. The ribbon menu will reflect the OpenRoads Modeling tools.

3. The Corridor file contains corridor RTE1 with template drop 2Ln_HMA.  The template drop applied only has two lane roadway surfaces without slope treatment.

4. Slope Treatment Linear Template can be applied to the edge of the road (EOR_lt and EOR_rt) as it is a 3D element with active profile.

5. Constructions option can be turned ON or OFF in the View Attributes window.

6. From Model Detailing Tab within the 3D Tools Group select:  Apply Linear Template.

7. Apply Linear Template dialog will open. Fill as below and then follow the prompts.

a.  Locate Element To Apply Template, click on the Left Edge of Roadway (EOR_lt)

b. Parameters: Template, click the browse button next to Template label to open Template library or click the Alt and Down to open Template library.

c. This opens the Pick Template dialog. Select the desired template prepared for the project and review. For this example, choose Project Library>Linear Templates>BCLC-w-cut-fill and click OK. 

d. Parameters: Template = Project Library>Linear Templates>BCLC-w-cut-fill, left-click to accept the BCLC-w-cut-fill

e. Parameters: Start = 0+00 (Click Alt to Lock to Start or type specific Station), left-click to accept. (This is same as 11+00 of RTE1 Baseline)

f. Parameters: End = 3+00 (Click Alt to Lock to End or type specific Station), left-click to accept. (This is same as 14+00 of RTE1 Baseline)

NOTE: Station entered here is the station related to EOR not the Base Line Station.

g. Parameters: Select Side-Reflect Option Mirror-<Alt> Down To Select, hover mouse right side of EOR_lt or as needed, left-click to accept.

h. Parameters: Exterior Corner Sweep Angle, 05° 00’00” (Default value, change as needed), left-click to accept.

i. Parameters: Description, BCLC_Grading_LT,  left-click to accept.

j. Right-click to exit command. Curb and Slope Treatment is generated at the Left Edge or Road. Corridor for the applied Linear template is automatically generated by the software.

k. The newly applied Linear Template can be reviewed from Explorer Window>OpenRoads Model.

8. Follow the same steps and Apply Linear Template at the Right Edge of Road.

Edit Linear Templates

Linear Templates can be edited as normal Templates, but it has its limitations. All the Corridor Parameter that can be edited for the Linear Template is less than that of Corridor.

This module instructs users how to edit or replace an existing Linear Template in the design file. When placing a linear template, a corridor is not needed, it can be applied to a 3D element.

1. See Apply Linear Template for required files and other information.

2. We are using a Corridor (Roadway Model) file that is used in above module.

3. An Applied Linear Template cannot be copied, so it needs to be reapplied as needed. To show contrast, in the current file the Linear Templates>BCLC-w-cut-fill (curb with slope treatment is applied at RTE1 Sta. 10+00 to Sta. 14+00) and the Linear Templates>BCLC-w base (only curb is applied at RTE1 Sta. 14+00 to Sta. 27+00) are applied at the left side of the Edge of Road.

4. When the template range of the Linear Template graphic is selected, the range can be edited as needed. The range can also be edited from the properties window by changing Start and End Station.

5. Change or swap the type of Linear Template, example: the BCLC-w-cut-fill to the cut-fill template.

a. Select: BCLC-w-cut-fill template and let the cursor rest on the element to access the context sensitive pop-up menu. Select Properties.

b. Click the Browse button in the right side of the Template Name label. This opens the Pick Template dialog.

c. Select the desired template prepared for the project and review. For this example, choose Linear Templates>cut-fill (grading only no curb) and Click OK.

d. The linear template processes with the new template. Notice the change in 3D view.

6. Edit linear template elements or parameters.

a. Select: cut-fill template and let the cursor rest on the element to access the context sensitive pop-up menu. Select Edit Template Drop.

b. Editing Roadway Designer Template Drop Window appears along with the existing template used at the template window i.e. Linear Template>cut-fill

c. The Template can be edited in various ways and reviewed. For this example, Slope and Horizontal Distance of Snow shelf can be changed.

d. Double click on SNOW_c point.

e. In the Point Properties dialog, change Slope Value as desired under Constraint 1 and change Horizontal Value as desired under Constraint 2 and click Apply, then click Close.

f. Click OK to close the Editing Roadway Designer Template Drop dialog.

g. The linear template processes with the new value.  Notice the change in slope and width of the snow shelf.

h. Similarly, other points or parameters of the Linear Template can be edited.

7. Edit the Corridor of a Linear Template.

a. Select the Corridor Handles of the cut-fill template and let the cursor rest on the element to access the context sensitive pop-up menu. Select the Corridor Creation Tools > Corridor Objects.

b. Corridor Objects Window will open. In this window the user can define four parameters as Parametric Constraint, Point Control, External Reference, and Clipping Reference.

c. Corridor edits for Linear Templates is less powerful compared to Placing and editing Corridors (shown below).
