Dear Sanjay Pandey,

I am not sure whether ElementIntersectsElementFilter works directly with linked docs. I'll check for you.

Here is one possible approach to determine the location of the linked elements in the host document:

You could use that as part of your solution.

Cheers,

Jeremy

Thank you for sharing!

ElementIntersectsElementFilter does not work with lilnked docs

but we can always loop the linked docs and use ElementIntersectsElementFilter with each linked doc.

Thanks & Regards

Hi Sanjay,

How exactly did you make it to work? I'm in a similar situation and for me it is not working.

I have an element from a linked doc and another one from current doc and ElementIntersectsElementFilter fail to see the intersaction.

This is what I'm doing:

FilteredElementCollector collector = new FilteredElementCollector(element.Document, new List<ElementId> { element.Id });
collector.WherePasses(new ElementIntersectsElementFilter(elementFromLink));

and collector.GetElementCount() return 0

Thank you,

Claudiu

Here it goes:

foreach (Document linkedDoc in doc.Application.Documents)
                {
                    FilteredElementCollector collectorn = new FilteredElementCollector(linkedDoc);
                    collectorn.WherePasses(new ElementMulticategoryFilter(builtInCats));
                    ElementIntersectsElementFilter testElementIntersectsElementFilter = new ElementIntersectsElementFilter(intersect);
                    collectorn.WherePasses(testElementIntersectsElementFilter);
                    foreach (Element elm in collectorn)
                    {
                        //string gt = elm.Id.ToString();
                        //TaskDialog.Show("IIPL", gt + "source " + intersect.Id.ToString());
                        got = true;
                        break;
                    }
                    if (got == true)
                    {
                        break;
                    }
                }

Thanks & Regards

This filter only work when your linkrevitinstance do not have transform to the current project.

You can check by the method RevitLinkInstance.GetTransform().

I feel annoying about this limitation now.
