PolyCurve from a Pipe Network

Revit
#1

I am trying to get a polycurve from a pipe network in my Revit file. I could not find another way to get the centreline (as a polycurve) of this network other than following the below workflow.

However, there are two problems with the workflow when:

  1. The piping is not drawn at one go i.e. continuous element IDs of pipes are not there in Dynamo workflow and a polycurve could not be formed.
  2. joinTolerance (for the gaps between two pipes due to pipe fitting) is greater than a (short) pipe piece length.

Is there any other way I could get a clean polycurve without interruption/gaps so that I could utilize this polycurve to draw flex piping out of it?

Get the centreline of duct or pipes as curve

Where did the Custom node. PipingSystem all elements in network come from as it does not load when i download and open the script.

Hi,
I guess, it’s from the MEPover package.
