Getting centerlines of ducts in Dynamo

Geometry
1

I have a set of ducts in Revit and I need the centerline of these ducts as I want to attach some objects following their path. I have never worked with ducts and Dynamo before, so any help is appreciated. I tried the “Center_line_of_Revit_MEP_Pipe” package, but didn’t get it to work :confused:

Can you post some screen captures of your work and errors you might be getting? It will only help those trying to help you out.

Aah, nice. It only got me halfway though. I need points along the centerlines, as you can see me trying below. However, I end up with a bunch of empty lists. I might be using the wrong nodes.

Hi @Pal_Roe_Larsen

I don’t think its possible to get centerline from “Ducts - Centerline”. However you can get the ducts Centerlines from ducts like this:
