Highlight opening when it is cut, how?

Revit

Hello,

i try to highlight my openings to “green” when they are cut! But it works just for true not for false, why?

for any reason the “not cut” opening remains also in true… i use spring nodes…

this is the code… is it possible to simplify that… to a for loop where i just ask “IsCut” (?) and i get a list of all my openings …

import clr

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

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

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

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

elements = UnwrapElement(tolist(IN[0]))
out1 = []
cut_el = []

cutU = InstanceVoidCutUtils
for i in xrange(len(elements)):
	try:
		if cutU.IsVoidInstanceCuttingElement(elements[i]):
			cut1 = cutU.GetElementsBeingCut(elements[i])
			if cut1.Count != 0:
				cut1 = [doc.GetElement(id).ToDSType(True) for id in cut1]
			out1.append(True)
			cut_el.append(cut1)
		else:
			out1.append(False)
			cut_el.append([])
	except:
		out1.append(False)
		cut_el.append([])		

OUT = out1, cut_el

i tried this… i think i have to involve geometry, but i just need booleans!

import clr

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

clr.AddReference('RevitAPIUI')
from Autodesk.Revit.UI import *

clr.AddReference('System')
from System.Collections.Generic import List

clr.AddReference('RevitNodes')
import Revit
clr.ImportExtensions(Revit.GeometryConversion)
clr.ImportExtensions(Revit.Elements)

clr.AddReference('RevitServices')
import RevitServices
from RevitServices.Persistence import DocumentManager
from RevitServices.Transactions import TransactionManager

doc = DocumentManager.Instance.CurrentDBDocument
uidoc=DocumentManager.Instance.CurrentUIApplication.ActiveUIDocument


openings = UnwrapElement(IN[0])

output = []

for i in openings:
	output.append(i.IsVoidInstanceCuttingElement)
	
	
OUT = output

is this correct ? changed the “else” so i think get correct values…

can i comprehense this script ?

import clr

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

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

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

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

elements = UnwrapElement(tolist(IN[0]))
out1 = []
cut_el = []

cutU = InstanceVoidCutUtils
for i in xrange(len(elements)):
	try:
		if cutU.IsVoidInstanceCuttingElement(elements[i]):
			cut1 = cutU.GetElementsBeingCut(elements[i])
			cut1 = [doc.GetElement(id).ToDSType(True) for id in cut1]
			if cut1.Count != 0:				
				out1.append(True)
				cut_el.append(cut1)
			else:
				out1.append(False)
				cut_el.append(None)
	except:
		out1.append(False)
		cut_el.append(None)		

OUT = out1, cut_el
