Python input as list problem

Hi,

Sorry I am very new in python, I used the script below to find the elements inside a boundingbox, it works fine, but it only applies on one boundingbox. But I dont know how to edit the script to input a list of boundingbox :frowning:

Python script as follow:

import clr
clr.AddReference('RevitAPI')
clr.AddReference('RevitNodes')
clr.AddReference('RevitServices')
import Revit
import RevitServices
from Autodesk.Revit.DB import *
from RevitServices.Persistence import DocumentManager
clr.ImportExtensions(Revit.Elements)
clr.ImportExtensions(Revit.GeometryConversion)
doc = DocumentManager.Instance.CurrentDBDocument

#Preparing input from dynamo to revit
bb = IN[0].ToRevitType()
outline = Outline(bb.Min, bb.Max)
#filter = BoundingBoxIntersectsFilter(outline)
filter = BoundingBoxIsInsideFilter(outline)

collector = FilteredElementCollector(doc, doc.ActiveView.Id).WherePasses(filter)

OUT = [e.ToDSType(True) for e in collector]

Tyr this, I think your bounding box needs a little bit of offset to always include elements, in some cases, not all elements/ sub elements are filtered:

import clr
clr.AddReference('RevitAPI')
clr.AddReference('RevitNodes')
clr.AddReference('RevitServices')
import Revit
import RevitServices
from Autodesk.Revit.DB import *
from RevitServices.Persistence import DocumentManager
clr.ImportExtensions(Revit.Elements)
clr.ImportExtensions(Revit.GeometryConversion)
doc = DocumentManager.Instance.CurrentDBDocument

#Preparing input from dynamo to revit
bb = IN[0]
l = []
for w in bb:
	wall = w.ToRevitType()
	outline = Outline(wall.Min, wall.Max)
#filter = BoundingBoxIntersectsFilter(outline)
	filter = BoundingBoxIsInsideFilter(outline)
	collector = FilteredElementCollector(doc, doc.ActiveView.Id).WherePasses(filter)
	l.append(collector)

OUT = [[i.ToDSType(True) for i in e] for e in l]

Hi @newshunhk ,

Whenever I encounter something like this I just wrap the Python code into a Custom Node with:
Input > Python Block > Output inside my Custom Node.

Then afterwards I just set that node to @L2 and it works with lists :slight_smile:

Hello

alternatively you can use build a filter that contains a set of filters with ElementLogicalFilter Class

import clr
import sys
import System
from System.Collections.Generic import List
clr.AddReference('RevitAPI')
clr.AddReference('RevitNodes')
clr.AddReference('RevitServices')
import Revit
import RevitServices
from Autodesk.Revit.DB import *
from RevitServices.Persistence import DocumentManager
clr.ImportExtensions(Revit.Elements)
clr.ImportExtensions(Revit.GeometryConversion)
doc = DocumentManager.Instance.CurrentDBDocument

#Preparing input from dynamo to revit
lstBbx = [ds_bbx.ToRevitType() for ds_bbx in IN[0]]
listFilter = List[ElementFilter]([BoundingBoxIsInsideFilter(Outline(bb.Min, bb.Max)) for bb in lstBbx])
filter = LogicalOrFilter(listFilter)
collector = FilteredElementCollector(doc, doc.ActiveView.Id).WherePasses(filter).ToElements()

OUT = collector
