Cable tray byline tunnel

Revit

Good morning, I have to model cabletray in a 4km long tunnel. How can I do this?
Is there a dynamo script that can help me?
Thanks

Hi Benedetta, welcome :wave:
Please take the time to read the forum FAQs

Start by getting the tunnel alignment and then work out your offset relative to the line coordinate system. It might also be possible to create a polyline with points, translate the Z value and then offset in the xy plane to the cable tray position.

Then use a CableTray.ByLines node - working example here

Hi Mike, thank you for the answer.
I tried the script but I can’t find these nodes.

Can you tell me in which package I find them?

Thank you.

They are there as part of the core nodes just that they have been renamed. Try searching for “Element Classes” and “All Elements of Class”

Ok. I try the scrip shared here but this is the result

When taking screen shots of the workspace, you can zoom in so that the nodes are readable and use Workspace from Export as Image menu

The overlay indicates the status of a node when they are small - the purple indicates it is from a package
