Conduits from CAD Lines

Revit

Hello,

I’m looking for some help with a Dynamo script that converts AutoCAD lines into Revit conduits.

I’m currently facing two issues:

  1. Only one conduit is being created – The script is placing conduit along only a single line instead of creating conduit for the entire CAD line path.
  2. The CAD.CurvesFromCADLayers node from Bimorph Nodes is no longer working, likely because it is outdated. Is there a recommended replacement node or workflow for extracting CAD geometry by layer in newer versions of Dynamo/Revit?

Has anyone encountered a similar issue or found an effective alternative approach for converting CAD lines into Revit conduits?

Any guidance or suggestions would be greatly appreciated.

Thank you!

do you have the latest bimorph package installed ?? then it should work i guess…but not 100% with 27 maybe we can ask @Thomas_Mahon
and PS for multiple try set lacing to longest in the create conduits node

@sovitek Thank you for your response.

  1. I set lacing to longest and it worked… almost. It is placing conduits but not connecting them. See screenshot below.

For this I used the following script:

2. For bimorph package this is the error I am getting plus the version I have installed (I’m working in Revit 2026):

@sovitek

So, what I have done is uninstall and reinstall the package now it shows me the correct 6.0.3 version. Thank You!

Now a new problem is occurring :smiling_face_with_tear:, It’s not placing all the conduits again even though the Conduit.ByLines is set to longest lacing. It is recongnizing all the lines but only placing some, any ideas on how to fix this? See screenshots below:

nope not really…but there is no reason for build the curves again…with start,endpoint you already have these curves…and try with a flatten, before you feed into the create conduits node…my old eyes cant see whats really goes on…iim on vacation, and only have sunclasses in the moment…hahaha

Thanks for your help! You are amazing! Enjoy your vacation.
