Filter Element Collector

I am trying to make a collector in python that collects all elements placed in model. I am using doors for this. Is there a way to get all doors placed instead of all placed doors and family types in the model?

import clr

#Import Revit Nodes
clr.AddReference("RevitNodes")
import Revit
clr.ImportExtensions(Revit.Elements)

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

# Import DocumentManager and TransactionManager
clr.AddReference("RevitServices")
from RevitServices.Persistence import DocumentManager

#The inputs to this node will be stored as a list in the IN variables.
doc = DocumentManager.Instance.CurrentDBDocument

#Filtered Element Collector
collector = FilteredElementCollector(doc)

#Quick Filter
filter = ElementCategoryFilter(BuiltInCategory.OST_Doors)
doors = collector.WherePasses(filter).ToElements()

#Assign your output to the OUT variable.
OUT = doors

Have a look at this bit of code from @solamour’s DynamoPython repository:

Note that there are several additional bits to this filter which you aren’t using (by view, of class), but they’re good to know about.

The specific part you need is the not element type method - .WhereElementIsNotElementType()

There is also the opposite if you leave out the word Not from it.
