Workflow: Create a Tunnel Design
Import into your project a tunnel design created in Trimble Access and contained in a TXL (.txl) file. Then, optionally, edit the tunnel design as necessary. Or, create a tunnel design "from scratch" directly in TBC that can be imported intoTrimble Access or another TBC project. Following are the basic steps for this workflow. For more detailed instructions, see Create a Tunnel Design or Create a Vertical Shaft Tunnel Design.

Steps: |
|
Commands: |
|
1. |
Use the Create Tunnel Alignment command to build a horizontal alignment (HAL) for the new tunnel design by entering values from engineering designs to define horizontal segments or curves at Points of Intersection (PIs). You can also create a HAL using the geometry of a line that you import or create. If needed, you can then define station equations and/or create a vertical alignment (VAL) using Vertical Points of Intersection (VPIs). (Not applicable for vertical shaft tunnels.) |
|
|
2. |
Use the Create Tunnel Corridor command to create a corridor for the tunnel that is defined by a horizontal and, optionally, vertical alignment and supports the insertion of tunnel shapes at specified stations along the corridor. (Not applicable for vertical shaft tunnels.) |
|
|
3. |
Use the Create Tunnel command to create a tunnel design based on the newly created tunnel corridor. Or: Use the Create Vertical Shaft Tunnel command to create a vertical shaft tunnel design. Vertical shafts are common in tunnel and underground mining construction to allow construction or extraction to be started at lower depths. |
|
|
4. |
Use the Create Tunnel Template command to create a template that can include one or more tunnel shapes that are applied at a specific tunnel station. Multiple tunnel shapes defined in the same template can be used create multiple tunnel "layers." |
|
|
5. |
Use the Create Tunnel Shape command to create shapes used to define the tunnel cross-section geometry along the tunnel alignment. |
|
|
6. |
Use the Add Tunnel Template Position command to apply a tunnel template to specific tunnel station, in addition to the station specified when you created it. This is useful if you want to switch from one template to another along the tunnel alignment and then switch back to the first template. |
|
|
7. |
Optionally, use the Create Designed Tunnel Mesh command to create a 3D mesh surface as a visual aid in viewing the shape of a tunnel design in the 3D View, where you can view the tunnel from various perspectives and use the Walk-Through View and 3D Drive View to further explore the interior and exterior of the tunnel. |
|
|
8. |
Optionally, use the Edit Tunnel Rotation command to rotate the tunnel by specifying rotation values at multiple stations along the tunnel corridor. |
|
|
9. |
Optionally, use the Edit Tunnel Vertical Offset command and/or Edit Tunnel Horizontal Offset command to specify a vertical and/or horizontal offset from the tunnel alignment centerline to apply at one or more stations along the tunnel corridor. |
|
|
10. |
Optionally, use the Edit Set Outs command to specify locations on a template for reference points at stations along the tunnel corridor. Reference points can be used to assist in construction of the tunnel (for example, radial points and blast-hole points). |
|
|
11. |
Use the Tunnel View command to view the properties and changes in the shape of the tunnel along its entire length. |
