6 6. Select the Create Corridor tool. Following the heads up prompting: a. Locate Profile - Reset For Active Profile: Click Reset mouse button b. Corridor Name: Type North St.and click Data mouse button to accept. c. Template: Hold down the ALT key and press the down arrow key to open the Pick Template window. Browse to and select the Templates > Urban > 2 Lane Urban Curb and Gutter with Sidewalk template. Click OK. Click Data mouse button to accept template d. Start Station: Type [1+045] and press the Enter key, then click Data mouse button to accept Note: Starting at this station to leave room for intersection civil cell. e. End Station: Press ALT key to lock to the end of the alignment, then click Data mouse button to accept. f. Interval: Type 10 [3] and click Data mouse button to accept. g. Minimum Transition Before Drop: Type 0 and click Data mouse button to accept. h. Minimum Transition After Drop: Type 0 and click Data mouse button to accept. The corridor model is displayed. The corridor model is built in a 3D model in the active DGN file. The 3D model is automatically referenced into the 2d model you are currently using. For now, we will turn off the display of the 3D model reference. 5

7 7. If not already off, turn off the display of 3D model reference in View 1. a. Select the References tool. b. Select the North St. file. Notice the Default-3D name in the Model column. c. Clear the Display setting by either clearing the check mark in the display column or selecting the icon at the bottom of the window. d. Close the References window. Notice that the corridor model is chorded around the curve. Corridor Models have a Design Stage property that affects how the corridor is modeled. The interval specified when the corridor is created defines the distance between drop points where the corridor is modeled. The Design Stage property applies a multiplier to the interval. For example, a Preliminary design stage has a multiplier of 10. So instead of our model being processed every 10 [3m] as we specified, it is modeled every 100 [30m].This is what causes the chording.early in a project using the Preliminary design stage causes the corridor to process faster and typically provides sufficient detail. As the project progresses changing to the design or final design stage results in a more accurate model. 8. Change the corridor to use the 2-Design design stage. a. Select the Element Selection tool. b. Select the corridor boundary element. The corridor boundary is the graphical shape that represents the extents of the roadway model. Sometimes it is easiest to select the corridor boundary by one of the lines that extends perpendicular to the border. c. Hover over the selected corridor boundary and click the Properties button on the context menu. d. Change the Design Stage to 2 Design. The corridor model updates. Notice that the chording is no longer present because the interval is now closer together. The 2-Design design state has an interval multiplier of 2 so the corridor is being modeled every 20 [6m]. 6

8 View Corridor Cross Sections OpenRoads utilizes a dynamic cross section model that presents a section view of the 3D model. These sections will include any 3D data that is actively displayed in the 3D model. This dynamic section view is not intended to produce the plan production sections. There is a separate Create Cross Section command for creating cross section sheets. 1. Select the Element Selection tool. 2. Select the corridor border. Sometimes it is easiest to select the corridor border by one of the lines that extends perpendicular to the border. 3. Select the Open Cross Section Model tool. 4. Open View 5 by selecting the 5 button at the bottom of the screen. There is nothing special about view 5, you can use any of the eight views. 5. Click inside view Select the down arrow next to View Properties at the top of the window. 7. Set the Vertical Exaggeration to Click the left and right arrow icons at the top of the window to scroll through the cross sections. A light blue line in the plan view indicates the location of the cross section currently being displayed. 9. Close the cross section view. 7

9 Adjust the Corridor Model to Meet and Match the Existing Turn Lane Insert an additional template drop through the intersection, edit the components and add a point control for the matching edge of pavement The current template is a fixed width and cross slope. In this exercise, we will need to adjust the cross slope to meet and match the existing pavement through the turn lane section of the corridor. We will add an additional template drop and remove the curb, sidewalk, and end conditions through the intersection as well as control the elevation of the edge of pavement to match the existing pavement. By using a point control, the edge of pavement template point can be aligned with the geometry element horizontally and vertically. In the following image, the blue edge of pavement, yellow curb, and purple sidewalk graphics generated from the corridor can be seen cutting through the turnout section. 1. Expand the Corridor Modeling task menu and select the Copy Template Drop tool. 2. In View 1, follow the heads-up prompts and select the template drop graphic along the corridor. 3. Continuing to follow the heads up prompting... e. Start Station: Type [1+107] and press the Enter key, then click Data mouse button to accept f. End Station: Type [1+229] and press the Enter key, then click Data mouse button to accept 8

10 Now, we will edit the additional template drop through the intersection area. We have the ability to edit the actual template used in the corridor with out impacting the original template in the template library. This is an important technique to use when modeling real-world scenarios where roadway conditions may vary along the corridor. In our scenario, we will remove the curb\gutter, sidewalk and end conditions from the template through the intersection. 4. Select the new template drop graphic that we created in the previous step. On the context menu, select the Edit Template Drop tool. 5. The Editing Roadway Template Drop window opens. This allows us to edit the template directly in the corridor for project-specific adjustments. 6. Right click anywhere in the open space within the template window. 7. From the menu, select Delete Components. 9

11 8. Data point (Left Click) in the screen and draw a line through the components you wish to delete. 9. The components are removed from the template. TIP: If a component is mistakenly deleted, you can UNDO the command by keying in CTRL + Z on the keyboard. 10. Click OK in the upper right corner. 10

12 11. The corridor is updated. We ve removed the curb and gutter, sidewalk, and end conditions from the corridor through the intersection. Now, we have to consider the vertical aspect of matching the new pavement to the existing pavement through the intersection and turn lane. Using OpenRoads, we can cut a profile along any element within the model. 11

13 Review the Profile of the Existing EOP We need to profile the match line feature and review the vertical alignment that will control the Edge of Pavement point within the roadway template to match the existing pavement through the intersection. 1. Click the Element Selection tool in the Tasks menu. The Element Selection tool is used to pick elements so they can be edited or manipulated with other commands. 2. Set the Element Selection tool to the individual mode by selecting the Individual and New icons in the Tool Settings window. 3. Hover the cursor over the Edge of Pavement feature to profile. As you hover over the feature, you ll notice that an informational box is displayed. You will have to reset (Right-Click) to select the proper feature. The correct feature is named MATCH EOP. TIP: Since we ran the Corridor Modeler first, we actually have 2 features in the model along the turn lane area. Therefore, you may have to right click to cycle to the proper feature. While hovering over the element, right click (reset) to cycle the selection to the next feature under the cursor, then left click (data point) to select the correct element. 12

14 4. Open the profile model and review the vertical definition of the point control feature. a. On the context menu that opens, select the Open Profile Model tool. b. Open an additional view or click into an existing open view to place the profile model. 13

15 Create a Corridor Point Control After reviewing the vertical control alignment, we will update the corridor model so that the LT_EOP template point follows the profile of the MATCH EOP feature through the intersection. 1. Review the 3D model (View 2) and notice that the corridor s LT_EOP feature and pavement does not follow the MATCH EOP feature. 14

16 2. Open View 4 and Use the Open Cross Section Model tool to review the cross sections and observe the cross slopes through the turn lane area. NOTE: To review a specific cross section along the corridor, Right Click in the cross section model window. Then select Locate Station Via Datapoint and follow the heads up prompts. 3. Select the Element Selection tool. 4. In View 1, select the corridor border. Sometimes it is easiest to select the corridor border by one of the lines that extends perpendicular to the border. 5. Click on the Corridor Creation Tools button. 6. Select the Corridor Objects tool. 7. Select Point Control from the Corridor Objects window. 15

17 8. Select the Add New tool. Following the heads up prompting... a. Start Station: [1+107] b. End Station: [1+229] c. Control Description: Control to MATCH EOP d. Mode: Vertical e. Control Type: Linear Geometry f. Point: LT_EOP This is the name of the point in the template that will be tied to the geometry element. It might be easiest to select this point name from the tool settings dialog instead of the heads up interface. g. Locate Plan or Profile Element: select the cyan vertical control alignment in the profile view. h. Priority: 1 16

18 i. Start Vertical Offset: 0 j. Stop Vertical Offset: 0 The Point Control is listed in the Corridor Object window and the model is reprocessed. Review the 3D model (View 2)and notice that the corridor s LT_EOP feature now follows the profile of the MATCH EOP feature. 9. Close the Corridor Objects window. 17

19 10. Using the Cross Section Model, review the cross sections again and observe the cross slope changes through the intersection. NOTE: To review a specific cross section along the corridor, Right Click in the cross section model window. Then select Locate Station Via Datapoint and follow the heads up prompts. 18

20 Exercise 2: Review the 3D Model Description This set contains exercises to review the 3D corridor model. Skills Taught Open View Define which model is displayed in a view using the View Attributes Define how the graphics in a view are displayed or rendered using the View Attributes Rotate in a 3D view 19

21 Review the 3D Model The corridor modeling process builds a 3D model by default. Generally you will be working in a 2D drawing and just look at the 3D model when you want to view the model. The 3D model can be viewed in any of the 8 views. 1. Make View 2 active. Or open View 2, if it has not been opened. 2. Select the View Attributes icon. 3. Change the Models to Default 3D. 4. Change the Display Style to Smooth. 5. Close the View Attributes window. 6. If the model is not visible, select the Fit View tool at the top of the window. 7. Zoom in near the left edge of the North St. corridor model. 8. Select the View Rotation tool at the top of the window. 9. Position the cursor over the centerline at the left edge of the corridor model. 10. Snap to the centerline by pressing the left and right mouse buttons at the same time. Hint: Some computers are setup to use the mouse wheel or center button to snap instead of the left and right button combination. 11. Press the data (left) mouse button to begin view rotation. 12. If the view cannot rotate as far as you want before the cursor exits the view window: a. Press the data (left) mouse button to stop view rotation. b. Move the cursor near the center of the view. c. Press the data (left) mouse button to begin view rotation again. 20

22 If you zoom in close enough you can see that this is a true 3D model of the corridor complete with subsurfaces, pavement layers, curb and sidewalk. You may alter the display of the model by changing the Display Style within the view. 13. Select the View Attributes icon. 14. Change the Display Style to Transparent. 15. Close the View Attributes window. 16. Review the model using the Transparent display style. 21

23 Exercise 3: Modeling an Intersection with a Civil Cell Description This set contains exercises for modeling a T intersection complete with curb returns and side slopes using a civil cell. Skills Taught Create a T intersection by placing a Civil Cell Change the curb return radii by editing the Civil Cell Tie the Civil Cell and secondary corridor together by moving the template drop location Cleanup intersection of Civil Cell and mainline corridor by copying and editing template drops. View 3D Model 22

24 Place a Civil Cell In the following exercises you will use a civil intersection cell to tie between the South Blvd. edge of pavement and the North St. template. Before placing the intersection cell we will delete the North St. superelevation so it matches a more real world configuration. 1. Continue in the North St.-Corridor-*****.dgn file used in the previous exercises. We will place the civil cell in View 1. View 1 is a 2D view that includes the North St. geometry and corridor model. We can work in the 2D view while simultaneously working in the 3D model. 2. Expand the Civil Cells Toolbox in the Tasks menu. 3. Select the Place Civil Cell tool. The tool settings window shows the name of the active civil cell. The Place Civil Cell tool automatically defaults to the last civil cell used and thus the dialog is locked (grayed out). 4. Press the Reset mouse button to unlock the active civil cell. 5. Select the button to open the Pick Civil Cell window. 6. Browse to and select the T-Intersections > Basic T civil cell. 7. Click OK. 8. Following the heads up prompting: a. Locate Reference Element: Secondary Road CL: select the red centerline for North St. b. Locate Reference Element: Through Road EP: select the blue edge of pavement for South Blvd. c. Select Elements to View Alternatives: press the Reset mouse button to skip The civil cell can be oriented differently to meet your geometric configuration. In this exercise the cell is automatically oriented correctly so all you need to do is reset to accept the orientation. 23

25 d. Select Corridors to be Clipped: press the Reset mouse button to complete If the South Blvd. corridor model was located in the active file, the Civil Cell can automatically clip the South Blvd. corridor where it overlaps the civil cell. In this exercise dataset the South Blvd. is located in a different file and is referenced into the active file. This is a common workflow for larger projects. In this configuration we will manually clip the South Blvd. corridor later in the exercise. e. Press Data mouse button to accept civil cell placement. A gap exists between the end of the intersection cell and the North St. corridor model that must be closed. 9. Select the Element Selection tool. 10. Select the Template Drop Handle for the North St. corridor. The Template Drop Handle is on the left (looking up station) at the beginning of the corridor. 24

26 11. Select the Start Template Drop manipulator arrow. 12. Position the cursor over the centerline at the end of the intersection cell and pause until the thick yellow snap graphic appears indicating that you are snapped to the end of the intersection cell centerline. 13. Click the Data mouse button to accept. The gap between the intersection cell and the corridor is healed. 25

27 Review Intersection 3D Model 1. If not opened already, open View 2 and set up as defined below. 2. Change view attributes to show 3D model. a. Select the View Attributes icon. b. Change the Models to Default 3D. c. Change the Display Style to Illustration: Ignore Lighting. d. Close the View Attributes window. 3. Adjust levels displayed a. Open the Level Display tool. b. Turn off the display of the Default level. Hint: The Default level may be the active level. The display of the default level cannot be turned off so you might need to double click on another level to set it as active first. c. You may want to turn off the levels that contain linear graphics so only the 3D model is visible. The following levels should be displayed. Grade_Cut Grade_Daylight Grade_Fill Grade_Veg_Grass Road_Curb Road_Pave_Aggregate Road_Pave_Concrete Road_Pave_Subbase Road_Sidewalk 26

28 4. If the model is not visible, select the Fit View tool at the top of the window. 5. Rotate the drawing to view the model. Hint: If you get lost while rotating the view, select the Top View or one of the other preset view rotations. 27

29 Adjust Curb Return Radius and Profile The T intersection civil cell places a 35 [12m] radius curb return by default. However, this radius can be easily adjusted as needed. 1. Set the plan and 3D model views so you can see the south curb return in both similar to the following image. This view configuration will allow you to see the 3D model update as you update the 2D geometry. Levels can be used to turn off the South Blvd. roadway model in the 3D model view. To do this, activate the 3D model view, open the Level Display menu, select the South Blvd - Imperial.dgn and turn off all of the levels. 28

30 2. Select the Element Selection tool. 3. In View 1, Select the blue edge of pavement line in the curb return. The geometry manipulator text appears. 4. Click on the Radius manipulator text. 5. Change the radius value to 50 [15] and click the Enter key. The horizontal geometry and 3D model update. 6. The profile of the Edge of pavement feature can be revised as well. d. In View 1, Select the blue edge of pavement line in the curb return. e. Hover over the element till the context menu appears. f. Select Open Profile Model from the context menu. If not open already, open View 3 and click into the view to place the profile. g. You will see the existing terrain line, as well as the profile for the edge of pavement feature. Using the vertical geometry tools, select Profile Line Between Points and create a new linear profile that runs the length of the profile. h. Select the new profile element and hover until the context menu is displayed. Click the Set as Active Profile button. The 3D model in View 2 is updated based on the new active profile. 7. Select File > Save Settings. Save Settings stores how the views are currently setup so that when you return to this file the 3D view will still be setup and visible. 29

31 Cleanup South Blvd. - North St. Intersection Overlap Currently the South Blvd. corridor overlaps the North St. Intersection. For a cleaner design model the South Blvd. corridor needs to be cleaned up through the area of the intersection. 1. Change to the South Blvd.file. a. Select File > Open. b. Select the South Blvd. - Imperial.dgn [South Blvd. - Metric.dgn] file. 2. Turn on all levels a. Select the Level Display tool. b. Enable all levels EXCEPT Draft_Corr_Superelevation. 3. Attach as a Reference the North St. file (with the intersection and corridor you created). Be sure Snap and Locate locks are enabled and the Nested Attachments is set to No Nesting. Hint: If you are not sure of the North St. file name, select the File menu. At the bottom of the menu is listed recently used files. The file in position 2is the North St. file you were most recently using. 4. Zoom in on the upper left portion of the alignment where North St. intersects South Blvd. 5. Create new Template Drops on South Blvd. where the curb returns intersect the edge of pavement. These two new template drops will use the same template as currently defined through this segment of South Blvd. so they overall design of the roadway will not change. The template through the intersection can then be edited to remove the curb, sidewalk, and side slopes through the intersection a. Select the Element Selection tool. 30

32 b. Select the Template Drop boundary around South Blvd. and hover until the context menu to appear. c. Select the Copy Template Drop tool. d. Following the heads up prompting; select the Start Station by snapping the end of an element in the northern curb return. 31

33 e. Select the Stop Station by snapping to the end of an element in the opposite curb return. The South Blvd. corridor now has to new template drops located at the exact ends of the intersection cell. 6. Edit Template Drop to remove curb, sidewalk, and side slopes through the intersection. a. Select the new Template Drop boundary in the intersection and hover until the context menu appears. b. Select the Edit Template Drop tool. The template editor window appears showing the template being used at this template drop location (through the intersection). We need to delete the curb, sidewalk, and side slope components on the left side of the template. c. Right click in the template editor window and select Delete Components. d. Position the cursor near the left edge of the editing window and press and hold the data (left) mouse button. e. Move the cursor around drawing a white line. Any element that the white line touches is deleted when you release the data button. 32

34 f. Repeat as necessary to delete all of the components left of the edge of pavement. When complete, the template should look like the following image. g. Click OK. The South Blvd. corridor model is recalculated with the new template through the intersection area. 33

35 Exercise 4: Review and Enhance the Complete Model Description This set contains exercises for reviewing and enhancing the 3D model. Skills Taught How to change the display style of the model How to stencil 2D pavement striping onto the 3D model 34

36 View 3D Model The final model produced by OpenRoads can serve many purposes. These include design review, constructibility assessments, machine control, and visualization. In the following exercises we will look at utilizing the model for practical applications beyond the typical plan production work flows. 1. Open the North St file where you created the intersection and corridor. 2. Review the finished model in View 2. The view should still be open because you used the Save Settings command before exiting the file. 3. Change the Display Style to Smooth to see the rendering without the triangles. 4. Also, levels can be turned off to remove the linear elements from the model view. 35

37 Enhancing the Model with Pavement Markings 1. Continuing in the file, set View 2 active. We re shifting into performing our work in the 3D model, so be sure the view that contains the 3D model is active with your dgn file for the following exercises. 2. Reference a 2D pavement marking file into the 3D model. a. Open the References dialog box. b. Browse to the training directory and select the file Pavement Marking-Imperial.dgn [Pavement Marking- Metric.dgn] c. Set the Attachment Method to Coincident-World and click OPEN. 3.
