Split imported solids in subsolids

Hello all!
I need some help and I hope the question is not too difficult…

I have a 3D AutoCAD file and need to identify all the sub-solids composing it.
Once this is imported in Revit, I need to recognize the solid inside it as separated geometries and after that, I will transform them to single families.
Well… I have no idea how splitting the geometry in separate sub-geometries… any hints??
Just imagine that my final scope is converting all the boxes and the cylinder in the image as separate families in Revit.

Many thanks in advance!

I think you need the node: Geometry.Explode

that node explodes all the geometries in single surfaces; I need to have all the solids instead

But can’t you recreate the solids after you explode it with the separate surfaces with Solid.ByJoinedSurfaces

You can, but from my experience, that tends to recreate a single solid. There are some workarounds for this issue, but there’s gotta be a way to get seperate solids more simply; a way that doesn’t involve recreating them from extruded surfaces and polylines. That approach is not always favorable with more complex geometry.
Has anyone had more luck with this?

@dcmasten1, so, did you find a way to solve this ?
I do have the same problem, made so research but quite a mess to find a proper solution !
