This will automatically toggle on the Alignment, Curves and Point List options. • In the Job Number dialog select job 100.gpk. • If required, Open the Set Feature tool and populate it as shown. • Follow the Prompts to correctly display the alignment with curve data and stationing.

  9. Session 6:Corridor Creation

  10. Corridor Creation Overview • Blend horizontal and vertical geometry with 3D topography and typical sections • View plan, profile, and cross section interactively • Provides heads-up dynamic, interactive parametric design • Manage one or multiple corridors for designs. • Preserve designer’s intent • Apply superelevation through text tables, customizable standards, or AASHTO standards • Reflect edits automatically in quantities and volumes • Updates of model are dynamic and automatic

  11. Hands-on Session: Create Corridor Model Workflow: • Create the corridor including template drops. • Customize the corridor to ascertain the required project settings. • Calculate superelevation and assign to the corridor. • Refine the corridor. • End condition exception – revise the default tie slopes by inserting a retaining wall at the left shoulder edge in the area bordering the existing lake.

  12. Steps: Create Corridor • Navigate to the folder ..\Session 6\ and open the file MainStreetDesign.dgn. • Select the Create Corridor tool and follow the heads-up display closely. • Locate Corridor Baseline = BASE1 • Reset for Active Profile • Corridor Name = BASE1 • Template = TxDOT > Project > Templates > Undivided 4 Lane With Shoulders Note <alt> + down arrow to navigate template library • Start Station = 0+00 (press <alt> key to lock to beginning of alignment) • End Station = 95+81.31 (press <alt> key to lock to end of alignment) • Drop Interval = 10 • Transitions = 0

  13. Steps: Design Settings • Select the corridor, hover and click Properties from the context menu. • Change the Design Stage to 2 – Design. • In view 1 (Default 2D Model), turn off reference display of the Default 3D Model.

  14. Hands-on Session: Superelevation Workflow: • Create superelevationsections. • Create lanes. • Calculate super transitions and assign to the Corridor. • Review data and adjust as needed.

  15. Steps: Create Superelevation Sections • Select the Create Superelevation Sections tool and follow the heads-up prompts. Note as you progress through the superelevation process, you are advanced automatically to the next tool. If you mistakenly reset out of the sequence, just select the desired tool from the Superelevation toolbox, and select the superelevation section when prompted. • Name = BASE1 • Locate Reference Element = BASE1 • Start and End Station – press <alt> to default to the begin or end of reference element. • Minimum Tangent Length = 5000

  16. Steps: Create Superelevation Lanes • After completing the superelevation section, the Create Superelevation Lanes tool is automatically invoked. • Lane Name = LT • Type = Primary • Side of Centerline = Left • Inside Edge Offset = 0 • Width = 24 • Normal Cross Slope = -2.0 • Repeat step 2 for the right lane, changing two parameters: • Lane Name = RT • Side of Centerline = Right
