Hi @shuzmm,  
Welcome to the Dynamo Community.  
I would recommend you always search the forum first. What you are searching for would probably be answered in some or the other way if you dig a little deeper!

A similar topic as yours already exists:

> 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…

And a possible solution would be:

```auto
import clr
clr.AddReference('RevitNodes')
import Revit
clr.ImportExtensions(Revit.GeometryConversion)

clr.AddReference("RevitServices")
from RevitServices.Persistence import DocumentManager
doc = DocumentManager.Instance.CurrentDBDocument

def tolist(obj1):
    if hasattr(obj1," __iter__"): return obj1
    else: return [obj1]

def GetBB(tblks):
	BBoxArr = []	
	for tbs in tblks:
		bbox = tbs.get_BoundingBox(doc.ActiveView).ToProtoType()
		BBoxArr.append(bbox)
	return BBoxArr

TBlocks = tolist(UnwrapElement(IN[0]))
	
OUT = GetBB(TBlocks)

```
