Apply Surface Templates

Surface Templates is a closed shaped component of a Template. A Surface Templates can be applied to a terrain using the Apply Surface Template tool. Surface Templates are used to apply material thickness to the terrain surface. A Surface Template can be of a single component or composed of different components.

This module instructs users how to place a surface template in a design file for a project. For placing surface template, a terrain is needed.

1. Load the 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 Roadway corridor RTE1 with a roadway template drop. Around Sta. 15+85, a driveway is designed. We need to create a Terrain and apply a Surface Template to the Driveway in order to make it complete.

NOTE: Driveway Civil Cells can be placed and edited as needed at this location

 4. Create a Terrain out of the driveway components. Make sure that all the Driveway components have active profiles.

a. From the Terrain Tab Ribbon and within the Create Group, selectFrom Elements.

b. The Create Terrain dialog will open and then follow the prompts.

c. Set the following on the dialog box:

Feature Definition: Design Top (User can change as required)

5. Apply the driveway surface template to P_DRV terrain

a. From the Model Detailing Tab Ribbon and within the 3D Tools Group select:  Surface Templates > Apply Surface Template.

b. The Apply Surface Template dialog will open, follow the prompts.

c. Set the following on the dialog box:

Feature Definition: Enable Linear Features

ii. Apply External Clip Boundary: No

iii. Select Template - <ALT> Down To Browse Template: Press <ALT> Down Arrow or click the browse button next to Template label on Apply Surface Template box to open the Pick Template dialog 

iv. Select HWY Surface Templates\Bituminous Residential Driveway

v. Click OK to close Pick Template dialog.

vi. Left-click to complete selection.

vii. Data Point to accept selection: Left-click to complete

e. P_DRV Main surface template is created as shown in 3D view.

6. Designers can create separate Terrains and apply Surface Templates to Driveway Shelf and Driveway Main separately. This is up to the Designers.

Edit Surface Templates

Surface Templates can be swapped or edited as per the project requirement. This module instructs users how to edit the Surface Template applied in a design file for a project.

1. Load the Corridor (Roadway Model) file and Load the Template Library for the project.

2. In this file a Commercial Driveway Civil Cell is placed, and we will be editing the Surface Template applied to the Driveway. The Driveway consists of two separate Terrains (Driveway Shelf and Driveway Main) and the Bituminous Commercial Driveway Template is applied to both Terrains.

3. Click and select a Driveway Main Surface Template (1-P_DRV Main Surface Template) in the 3D View.

a. Open the Properties dialog and expand the Mesh Template group.

b. The current template is HWY Surface Templates> Bituminous Commercial Driveway.

c. Click the Browse button at right side of the Template Name label. This opens the Pick Template dialog.

NOTE: Alternatively, Select Driveway Main Surface Template (1-P_DRV Main Surface Template) in the 3D View and let the cursor rest on the surface to access the context sensitive pop-up menu. Select Properties. Quick Properties opens, Click  Browse button at right side of the Template Name label. This opens the Pick Template dialog.

d. Select the desired template prepared for the project and review. For this example, choose HWY Surface Templates> HMA_Pavement_Structure

e. Click OK.

f. The surface template processes with the new Template. Notice the change in the 3D view. The surface updated from 2 layers to 3 layers of pavement.

2. The User can edit the pavement thickness

a. Click and rest cursor (hover) over the Driveway Main Surface Template (1-P_DRV Main Surface Template) in the 3D View.

b. From the Context Tool Bar, select Edit An Applied Surface Template. 

c. In the Editing Roadway Designer Template Drop dialog, the pavement thickness can be edited.

d. For this example, EOR_sg_lt and EOR_sg_rt points depth will be changed from 1’ to 1.33’. 

e. Double click on EOR_sg_lt point.

f. In the Point Properties dialog, change Vertical Value from -1 to -1.333 under Constraint 2 and click Apply then click Close.
