ElementIntersectsElementFilter is not working for Lineked documents elements.

[s04049]

Hi

I am trying to find the intersect element between the selected element with the link file element.

When running the [Current_document] with [Current_document_element]

FilteredElementCollector(Current_document)

everything is fine.

However running the [Link_document] with [Current_document_element]

FilteredElementCollector(Link_document)

nothing filters to result from the list

List<Element> resultele = new FilteredElementCollector(Link_document).WhereElementIsNotElementType().WherePasses(new ElementIntersectsElementFilter(Current_doc_element)).ToList();

I found this post on forums that says this is a software glitch.

I try to run on 2023 and 2021 and still get the same result.

I am unsure whether you can run an ElementIntersectsElementFilter to directly analyse the current document with a linked document.  Afaik, a filtered element collector can only work in one document at a time.  If you are interested in a limited set of elements in either one of the two documents, you can retrieve their solid geometry, transform it to the other document coordinate space and use a ElementIntersectsSolidFilter on that instead.
