Does BoundingBoxIntersectsFilter work for text note?

[mycad2016D8W4P]

I created two overlap text notes in a document, and run the code below, seems BoundingBoxIntersectsFilter does not work for text note. What's wrong? Any other easy way to check if text notes are interesected? Thanks. RevitDb.FilteredElementCollector collectorNotes = new RevitDb.FilteredElementCollector(Document.RevitDoc) .OfClass(typeof(RevitDb.TextNote)); var notes = collectorNotes.ToElements(); foreach (RevitDb.TextNote note in notes) { var view = Document.RevitDoc.GetElement(note.OwnerViewId) as RevitDb.View; var box = note.get_BoundingBox(view); var ol = new RevitDb.Outline(box.Min, box.Max); RevitDb.FilteredElementCollector collector = new RevitDb.FilteredElementCollector(Document.RevitDoc) .OfClass(typeof(RevitDb.TextNote)) .WherePasses(new RevitDb.BoundingBoxIntersectsFilter(ol)); var elements = collector.ToElements(); if (elements.Count > 0) { } }

I was trying the same thing a while ago. Here's what I know:

BoundingBoxIntersectsFilter only works on 3d Elements. 2d Elements are ignored.

What you can do, though you must decide for yourself if this is worth it, is the folowing:

For every textnote, use it's bounding box to create a new 3d Solid. This new 3d Solid will have the same dimensions ans position as the textNote, therefore you can use it as a subsitute for the textnote and use the BoundingBoxIntersectionFilter.

(Note: If you ever try this with Tags, please consider the fact that the boudingBox of a tag goes all the way from the tag itself to the tagged item, and thus is much larger than the tag itself).

Thanks. If so, I would check if the bounding box intersected one by one.
