Workflow for Importing & Updating Tunnel Alignment from Civil 3D to Revit

[Guillermo_Co]

Hello everyone,

I’m working on a tunnel project and looking for the best workflow to:

Import an alignment and profile from Civil 3D into Revit (via 3D polyline, XML, or any other method).

Model a tunnel in Revit that follows the Civil 3D alignment.

Ensure that when the alignment or profile changes in Civil 3D, the tunnel geometry in Revit updates automatically—either dynamically or through a Dynamo script, without the need for manual remodeling.

Does anyone have recommendations or experience with this kind of setup? Any guidance on tools, workflows, or scripts would be greatly appreciated.

Thanks in advance!

Look on AU 2015 for CI 11198_REVITalize Bridge Design. Dynamo needed.

That's probably the best we've seen so far, I would however reccomend modelling the tunnel in Civil3d first with a corridor to check the alignment, depths etc are correct before passing to revit for the structural design.

Thanks, Mike! That’s exactly the kind of direction I was looking for. I’m now considering either using Dynamo or SOFiSTiK Bridge + Infrastructure Modeler for this workflow. Appreciate the insight!
