BoundingBoxIntersectsFilter / IsInsideFilter

Hallo community,

maybe someone knows why the filter doesnt collect the elements within the boundingbox… ?
If I try to retrieve the elements without considering the boundingbox, it works out. Only when I try to retrieve the elements within the boundingbox, there is no output.
Revit view:

Code:

_linkDoc = IN[0]
_category = IN[1][0]

activeView = UnwrapElement(IN[2])

bbxMin = activeView.GetSectionBox().Min
bbxMax = activeView.GetSectionBox().Max

ol = Outline(bbxMin,bbxMax)

try:
	errorReport = None
	filter = ElementCategoryFilter(System.Enum.ToObject(BuiltInCategory, _category.Id))
	bbfilter = BoundingBoxIntersectsFilter(ol)
	andfilter = LogicalAndFilter(filter,bbfilter)
	result = FilteredElementCollector(_linkDoc).WherePasses(andfilter).WhereElementIsNotElementType().ToElements()
except:
	# if error accurs anywhere in the process catch it
	import traceback
	errorReport = traceback.format_exc()

#Assign your output to the OUT variable
if errorReport == None:
	OUT = result
else:
	OUT = errorReport

Try to get your code working without a try loop first. Otherwise you can’t see what error you’re getting.

I also tried out without the try / except and the output is again empty:

lnkDoc = IN[0]
category =UnwrapElement(IN[1])[0]

activeView = UnwrapElement(IN[2])

bbxMin = activeView.GetSectionBox().Min
bbxMax = activeView.GetSectionBox().Max

ol = Outline(bbxMin,bbxMax)

#category filter
catfilter = [ElementCategoryFilter(System.Enum.ToObject(BuiltInCategory, int(str(category.Id))))]

catfilterlist = List[ElementFilter](catfilter)
filter = LogicalOrFilter(catfilter)

#combining boundingbox and category filters
bbfilter = BoundingBoxIsInsideFilter(ol)
andfilter = LogicalAndFilter(filter,bbfilter)

#collecting elements

coll = FilteredElementCollector(lnkDoc).WherePasses(andfilter).WhereElementIsNotElementType().ToElements()

OUT = coll

oh, i found out the reason

lnkDoc = IN[0]
category =UnwrapElement(IN[1])[0]

activeView = UnwrapElement(IN[2])

bbx = activeView.GetSectionBox()
bbx.Max = XYZ(500,500,500)
bbx.Min = XYZ(-500,-500,-500)
#bbxMin = activeView.GetSectionBox().Min
#bbxMax = activeView.GetSectionBox().Max
bbxMin = bbx.Min
bbxMax = bbx.Max

ol = Outline(bbxMin,bbxMax)

I just redefined the boundingBox manually by giving other values and somehow the elements are retrieved, it means that bbx = activeView.GetSectionBox is not working out properly…

any ideas why?

It’s hard to say without seeing any of your inputs, but I would guess the view does not have a section box assigned or you’re not handling the view properly.
