HI Everyone,

I’m trying to collect elements hidden in views for which I tried

  1. collect elements from prject
  2. Use a python scipt that can find hidden elements in view

It works fine for elements in active view but if I try to collect all the elements from project,
"How do I filter those elements which do not have a specific attribute named “IsHidden” ?

Warning I get when I try run the script:

Script:

import clr
clr.AddReference('RevitAPI')
from Autodesk.Revit.DB import *

clr.AddReference("RevitNodes")
import Revit
clr.ImportExtensions(Revit.Elements)

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

def toList(obj):
    if hasattr(obj, '__iter__'): return obj
    else: return [obj]

elements = toList(UnwrapElement(IN[0]))
views = toList(UnwrapElement(IN[1]))
elementsHidden = []
elementsNotHidden = []

for view in views:
	for element in elements:
		if element.IsHidden(view) is True:
			elementsHidden.append(element.Id)
		else:
			elementsNotHidden.append(element)

OUT = elementsHidden

Any leads can be of real help :slight_smile:

Hey,

Have a look in Archi-lab? There is a custom node which unhides elements… you can have a look at the Python in there?

Cheers,

Hello
a few solutions

for view in views:
	for element in elements:
		if element is not None:
			if element.IsHidden(view):
				elementsHidden.append(element.Id)
			else:
				elementsNotHidden.append(element)
## OR ##
for view in views:
	for element in elements:
		if hasattr(element, 'IsHidden'):
			if element.IsHidden(view):
				elementsHidden.append(element.Id)
			else:
				elementsNotHidden.append(element)

or try to remove nulls from input list (elements) with OOTB node
