Array Surface in a Polycurve direction

Question

Hi all, 
 Is it possible to array a surface through a polycurve direction? 
 Thanks!

Hello Francesc, 
 I gave it a look and I would say that in this specific case the only way to have something similar would be if the tunnel was defined via the Tunnel Designer. 
 As I understand you have imported this geometry which would make the process of computing the normal of each surface quite tricky in PLAXIS, which is why I think you can continue doing that part on the CAD software.

Dear Francesc, 
 I confirm that with the Tunnel Designer you can only handle trajectories on a plane. Therefore the alternative is to import the trajectory as a polycurve in Structures mode (3D path is possible), create the cross-section surface and extrude this along this path (trajectory).

I would also choose to use CAD software for this as it is easier to create the whole geometry there and then import it in PLAXIS. 
 If you transfer the orthogonal surfaces (acting on the normal to the trajectory, if you can say that) in PLAXIS then I would make them larger than the tunnel so that the intersection is ensured when triggered. 
 I agree that overall having a 3D trajectory path via the tunnel designer will add value to the tool and it deserves to be considered in future implementations. I am sure that more would benefit from this feature, too.
