Hello everyone. I am a new dynamo user. I successfully thicken a surface of a floor along Z direction, and apply a boundingbox to that extrusion. The question is, is there a node that I can use to return all the elements(even without being selected in dynamo) contained inside the box?’ Thx!

Hi Po Chun,
Can you drop screenshot of your work. It will helps others to understand your issue. Thanks 
I am sorry. Actually what i want is to return the pipe elemnnts inside the boundingbox
Hi @pccheung
The node BoundingBox.Contains is probably what you’re looking for. It only works with points though :
In my example I used the midpoint of the location curves of the pipes…

Hi mostafa, Kulkul,
Thx for both of your comments. However, is there another way for locating the pipes WITHOUT SELECTING THEM, the only element I selected is the floor.
Thanks a lot.
I my example I didn’t select them, I got them all from the pipe category with the “categories” and “all elements of category” nodes
@Mostafa_El_Ayoubi I think @pccheung is looking to get elements (pipes) without using categories or selecting elements. I guess he wants to get elements inside boinding box without specifying.
Ha ha, it’s true. I am sorry that i didn’t make the question clear. Indeed I m trying to check the headroom above the selected floor. In a real project, there will be beams, pipes, ducts, cable tray …etc above the floor. Do you mean I can only got all those stuff through categories node?
Really, thx for your efforts!
Oh I see . Sorry for misunderstanding … I’m not sure how that could be done !
You can do something like this:
With FilteredElementCollector you get all elements in the (active) view. And with BoundingBoxIsInsideFilter or BoundingBoxIntersectsFilter you can filter out the elements inside the bounding box:
##Python code:
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]

Dear Einar_Raknes,
Thank you very much. I am gonna try it out. It’s fascinating!!! THX!
Dear Sir Einar_Raknes,
Sorry for being stupid, can me further explain to me what is the output of the python script note, because I use a watch node to check what it gives out, it shows me a null.
Oh Sorry, I quit and restart, it returns to normal. Sorry Sorry.
Hi,
Interesting topic. I have a similar question.
I have used this python script with a scope box and all works fine as long as i use the “Select model element” with one scope box. But i want to take this a step further by using categories to select all scope boxes. Then the issues starts. The script won´t run through.
So to my question… What am i doing wrong? Is it possible to repeat the script for each scope box?
I have tried to get around this but i do not manage to full fill my wish 
Is there anyone who has any ides what i´m doing wrong?

I wrote this in another topic: How to make a pyton script work with a list as input
Thanks for the fast reply.
Ok, so i have no experience with python or programming… i tried to read trough and understand witch part i should implement and i got this.
I did not work. Maybe you could point me in the right direction?
