Python - BoundingBox property returns indexer. How to get Element.BoundingBox?

[Justin_Wright]

I am trying to get the bounding box of an element so I can get the middle point.

I thought this would be the Element Property

Using this on a Room Element, python returns a
IronPyton.Runtime.Types.ReflectedIndexer
from which I can get the Max or Min points.

import clr

# import Revit Services 
clr.AddReference("RevitServices")
import RevitServices
from RevitServices.Persistence import DocumentManager
from RevitServices.Transactions import TransactionManager

# import Revit API
clr.AddReference("RevitAPI")
import Autodesk
from Autodesk.Revit.DB import *

doc = DocumentManager.Instance.CurrentDBDocument
rooms=FilteredElementCollector(doc).OfCategory(BuiltInCategory.OST_Rooms).ToElements()
bbox = rooms[0].BoundingBox

#bbMax=bbox.Max

OUT=bbox

This post on stackoverflow includes a function get_BoundingBox, which is not in the Revit API library. I have not seen an ‘_’ used in function names so suspect this is part of pyRevit?.

el_bb = el_ID.get_BoundingBox(doc.ActiveView)

How to get the bounding box from a Revit Element with Revit API, then call to center of that bounding box

I would like to be able to get the bounding box of the element using Python.

Thank you.

Does the get_BoundingBox() not work? I believe that Syntax is correct for python.

LocationPoint vs. BoundingBox, what do i call?

Hi @Draxl_Andreas, [2020-09-26_11h36_18] Your point values are in internal units of Revit. clr.AddReference('RevitNodes') import Revit clr.ImportExtensions(Revit.GeometryConversion) elements = UnwrapElement(IN[0]) points =[] for e in elements: bb = e.get_BoundingBox(None) if not bb is None: centre = bb.Min+(bb.Max-bb.Min)/2 points.append(centre.ToPoint()) OUT = points Add ToPoint() to convert in Dynamo Point. clr.AddReference('RevitNodes') import Revit clr.ImportExtensions(Revit.Geo…

Thanks Sean, I managed to get get_BoundingBox to work:

def GetCenterPoint(ele):
	bBox = ele.get_BoundingBox(None)
	return (bBox.Max + bBox.Min) / 2

I was using the function in a larger script… I think my issue is related to this post:

Python get_BoundingBox returns null

Hi, I’m using python to place a family instance on a point and trying to get its bounding box using get_BoundingBox(None) method. But BoundingBox for the Instance returns Null (as shown in A). Then I tried to use the same family instance to create bounding box in separate python script using same boundingbox method it works what am I doing wrong in Script A? [image] here is my code Version:0.9 StartHTML:00000097 EndHTML:00004693 StartFragment:00000199 EndFragment:00004655 import clr clr.A…

Where can I find documentation on the python Syntax for the API?.
