Creating a tunnel using Excel coordinates

Hi Venkatesh

I’m afraid I can’t share the complete solution as it was for a specific client/project.
However, refer this link for a sample Revit (2015) file- with just 200 rings- you can extract the adaptive family from there. For the Dynamo part, you basically feed in 2 points for each instance of the family (start and finish) The start point of one ring will be the finish of the one before it.

There a number of solutions in the public domain, using different approaches- some like mine use adaptive families, some use sweeps. You might need to take different approaches for the tunnel itself or things in the tunnel, like cable trays, lighting, track. Refer my post on cable trays below
