This movie shows how to define a tunnel, a trajectory and how to divide the trajectory in the to-be-excavated tunnel segments by using the new 3D Tunnel Designer available since PLAXIS 3D AE.

Since the initial release for PLAXIS 3D AE, we added more functionality:

• direct definion of rockbolts and umbrella arches in the Properties mode. See Using Rockbolts in the 3D Tunnel Designer
• added a new mode: tunnel sequencing to quickly setup your tunnel construction stages, see How to define an excavation sequence in Tunnel Designer and Tunnel advancement script for PLAXIS 3D
