SELECTING ELEMENTS CUT BY ACTIVE VIEW PLANE RETURNS NOTHING

[AGYEMANG.OFOSU]

I have an issue selecting beams that are cut by the view plane. Unfortunately the code returns nothing. 

public void Show()
		{
			UIDocument uidoc = this.ActiveUIDocument;
			Document doc = uidoc.Document;
			
			
			BoundingBoxXYZ box = doc.ActiveView.CropBox;		
			Outline outline = new Outline(box.Min, box.Max);		
					
			BoundingBoxIntersectsFilter beamintersect = new BoundingBoxIntersectsFilter(outline);	
			List<Element> beams = new FilteredElementCollector(doc, doc.ActiveView.Id).OfCategory(BuiltInCategory.OST_StructuralFraming).WherePasses(beamintersect).WhereElementIsNotElementType().ToElements().ToList();


			ICollection<ElementId> idc = new List<ElementId>();
			
			foreach (var element in beams) 
			{
				ElementId id = element.Id;
				idc.Add(id);
				
			}
			
			uidoc.Selection.SetElementIds(idc);
			uidoc.ShowElements(idc);

Hi @AGYEMANG.OFOSU,

I tried using your code and it works fine for me.

The problem may be with your bounding box.

Just increase the boundary of your bounding box and give it a try.

it does not work. I am trying to get beams parallel to the view direction and are cut by the view plane but it does not work. I have tried

Thankfully I had seen your solution before and it worked liked a charm. Grateful.
