Tunnel Intersection

The workflow for creating a tunnel intersection between main tunnel and secondary tunnel(s) is as follows:

User imports, creates or references alignments that will be used for main and secondary tunnels. Alignments can be created either by using the provided tools under Civil tab or by using Create Transverse Alignment tool.
User places the main and secondary tunnels. The tunnels can be conventional or mechanized (TBM) tunnels.
For detailed information's about modeling conventional tunnels, refer to this link: Conventional Tunnels Modeling
For detailed information's about modeling mechanized (TBM) tunnels, refer to this link: Mechanized (TBM) Tunnels Modeling
User starts Intersect Tunnels command.
User selects the main tunnel. The main tunnel is the one that will be cut by secondary tunnel at its intrados.
User selects one or multiple secondary tunnels.
User resets to complete and data point to accept.

Note: Excavation Subspaces and Shotcrete (Permanent Wall/Temporary Wall) elements that have been placed on main and secondary tunnels will also be cut after intersecting tunnels. The selection of the main/secondary tunnels will determine the position of the intersection. The main tunnel can be intersected with multiple tunnels in one single operation. The intersections can be reverted using the Erase Tunnel Intersections command.
