Get space an element is in from linked file

Hello chaps!

Question:

I have linked the architectural model room bounded it and trying to get the spaces a list of elements are in…

any thoughts?

Or how the get surrounding elements node works…

I feed it two list of elements… no?

I can find 4 related nodes that could be tested in this workflow:

Space.IsInSpace from DynamoMEP
Space.IsPointInside from Rhythm
Elements in Space from Archi-lab Grimshaw
MEP Spaces Element Collector from Dynamo4MEP

There are also workarounds with Geometry Intersect and Bounding Boxes…
