Collect all elements in a geometry

Hi all,

I want to collect all the element strictly inside a geometry. I already found a node that collect all the element (not strictly) in a bounding box. The problem is that the bounding box can not always define the exact geometry as it is align with the axis. So I don’t want to create a Bounding Box. And also, this node takes all the elements inside the bb but also the ones that intersect the bb (but are not completly inside the bb), I only want the ones strictly inside my geometry.
Any help to change the script please ?
Here it is :

import clr
import Revit
import RevitServices
from Autodesk.Revit.DB import *
from System.Collections.Generic import List
from RevitServices.Persistence import DocumentManager
from RevitServices.Transactions import TransactionManager
doc = DocumentManager.Instance.CurrentDBDocument

#Functions for list handling
def ProcessList(_func, _list):
   return map( lambda x: ProcessList(_func, x) if type(x)==list else _func(x), _list )

#Preparing input from dynamo to revit

def ToRevit(item):
	return item.ToRevitType(True)

if isinstance(IN[0], list):
	bblist = ProcessList(ToRevit, IN[0])
	bblist = [ToRevit(IN[0])]

def collectElementsInBB(bb):
	outline = Outline(bb.Min, bb.Max)
	filter = BoundingBoxIntersectsFilter(outline)
	collector = FilteredElementCollector(doc, doc.ActiveView.Id).WherePasses(filter)
	return [e.ToDSType(True) for e in collector]

OUT = ProcessList(collectElementsInBB, bblist)

Thanks !

Could you tell where does this code come from and what you tried to change in it?
See also here how to paste code in a post:

The code comes from this forum,
I tried to change the bounding box in a geometry and get the outlines of the geometry instead of the “(bb.Min, bb.Max)”,
I am not very good on python, just learning and so trying things.

Please add the link to the original post and point to the lines you tried to change with some explanation around. Thanks :slight_smile:

Have you tried to use a geometry.intersects node as a bool mask? Should be callable via Python.

Note that this will be much slower than the bounding box.contains node.
