Where to Start?

We recommend that you orient yourself to the product first by reviewing the Getting Started section of this help.

Next, it is recommended that you work through one or more of the tutorials. They will provide you with practical experience in using OpenTunnel Designer to model various "real world" tunnel projects.

Key Features

OpenTunnel Designer (OTD) CONNECT Edition 2022 Release 2 contains the enhancements and error corrections mentioned in the following paragraphs.

I. Enhancements

1. Reports: The auxiliaries and singularities placed as cell's are now listed in the quantities report.
2. Reports: Multiple enhancements for input echo report and quantities report.
3. Feature Definition: Added option to select a feature definition for the alignments created with tool "Create".
4. Feature Definition: Added the feature definition property panel on properties dialogs for reinforcements.
5. Drawings: Added option "Dynamic View by Station".
6. PLAXIS transfer: Added option to send multiple tunnels information in one single script file.
7. PLAXIS transfer: Support for ellipse geometry during transfer.
8. ProjectWise: Added ProjectWise installer.
9. ProjectWise: Multiple enhancements regarding the interoperability between ProjectWise and OpenTunnel.
10. Modeling: Improved placement time for TBM tunnels.
11. Modeling: Added option to define a theoretical excavation shape for portals defined as templates.
    Note: For previously created templates, the user will have to manually add the shape of the theoretical excavation in his template.
12. Modeling: Added option to tag multiple auxiliaries by point in one command.
13. Modeling: Enhancements regarding the soil meshes cutting.
14. Modeling: Enhancements regarding the solid creation on tight curves or specific alignment geometry.
15. Modeling: Added the option Auxiliary - Place by Station.
16. Modeling: The tag tool for auxiliary by path has been changed to support only closed boundaries (like tunnel lining parts) instead of a closed shape.
17. Modeling: Added the capability to support placement of parametric cells using OTD tools.
    Note: The cells will be placed using the variations from the cell file; the user will not be able to control the variations from the active model in OTD.
18. Modeling: Added the option "Set active alignment". The tool will move the tunnel from one alignment to another alignment.
19. Modeling: Added the option to place conventional tunnels and portals with the property "Vertical" (parallel with world Z direction) and "Normal" (normal to the active profile).
20. Modeling: Updated files in the tunnel catalog. Updated portal catalog files (added the excavation shape for portals).
21. Item types: Technology Preview - Added the possibility to attach item types to the feature definitions defined in OTD for tunnel solids.
    Note: The item types need to be attached to the feature definition prior to create the tunnel solid.
22. GUI: Added option to select multiple templates in the Tunnel/Portal Template dialog for export or delete commands.
23. GUI: Added a new tab called "Singularities" in the material catalog for selecting a material when placing singularities as cells.

II. Error corrections

1. Fixed an error where the soil was not filled after an element was deleted.
2. Fixed an error where the solid was not updating after the 2d geometry was deleted from the template.
3. Fixed an error where the soil meshes were not cutting correctly the tunnel that was passing through different soil meshes.
4. Fixed an error where in some specific cases the forepoles direction was not computed correctly.
5. Fixed an error where the soil meshes were not transferred correctly to PLAXIS 2D.
6. Fixed multiple errors regarding the soil meshes for different specific cases.
