Hi everybody,

I would like to know if I can replace wall foundations by structural framings as a foundation walls.

I know I can insert beams by a curve:  
[https://forum.dynamobim.com/t/create-lines-in-dynamo-and-convert-to-beams-in-revit/11794](https://forum.dynamobim.com/t/create-lines-in-dynamo-and-convert-to-beams-in-revit/11794)

However I don’t know how to get a curve from the center of a Wall or from the center of a Foundation Wall.

Thank you.

I think you could use the **Element.GetLocation** node. That will give you the curve that define a wall (the line you drew on Revit i you will). Also work with beams.

Thank you very much that works!

This solves a part of my problem.

I’m looking for a way to select the Foundation Wall that is hosted on the selected wall. I would like to do that for 3 reasons:  
1- Erase the existing Foundation Wall.  
2- Get and set the Mark parameter in the new beam.  
3- Get the dimension of the Fondation Walls to insert the correct new beam directly. (Perhaps I’m too ambitous 🤔)

Thank you.

I think [archi-lab](https://forum.dynamobim.com/t/revit-2022-dynamo-2-10-package-not-showing-up-and-icons-missing/62933/7?) package has a Element.delete node.

Don’t know how to do the other things you want to do 😕
