Looking for Catenary_Wire_Chat_RAIL.dyn or help creating a 3D railway catenary system in Dynamo

Civil 3D

Hi everyone,

I’m currently working on a project involving railway overhead contact systems (OHE) and I’m trying to automate the creation of the catenary wires using Autodesk Dynamo (with Civil 3D).

I came across a reference to a file named “Catenary_Wire_Chat_RAIL.dyn”, which seems to be related to this topic — but I haven’t been able to find it anywhere online.

:backhand_index_pointing_right: Does anyone have this file, or know where it can be downloaded?
Alternatively, could anyone share some guidance or examples on how to automatically generate a 3D railway catenary between OHE masts and cantilevers in Dynamo?

Any help, scripts, or workflow suggestions would be greatly appreciated!

Thank you in advance :folded_hands:

“I’m asking about this because I saw it in a presentation by Autodesk itself, and there they showed a .dyn file creating the catenary for a railway.”

“Thank you, I’ll have a look.”

Where did you see the presentation? Often it’s best to reach out to the presenters directly, as I have thousands of colleagues and we often bring in guests who are experts or doing cool things in a particular area and only that guest can provide their IP.

I had seen in this link “https://youtu.be/ajKhhIMJW_s?si=21wBobcP6bEuizBq” the presentation of Civil 3D 2020 - Dynamo Design Automation by Autodesk itself, at second 52… Since it was an official Autodesk presentation, I thought it wouldn’t be a problem. Thank you.

Not an issue at all - we just needed to know where it came from.

@zachri.jensen, before your time, but do you have any idea if we have this around somewhere still?

Not really sure. Might be something similar here?
