import clr
import sys
import System
from System.Collections.Generic import List
clr.AddReference('ProtoGeometry')
from Autodesk.DesignScript.Geometry import *
import Autodesk.DesignScript.Geometry as DS

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

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

doc = DocumentManager.Instance.CurrentDBDocument

filterAnnot = System.Predicate[System.Object](lambda x : x.Family.FamilyCategory.CategoryType == CategoryType.Annotation)
symbAnnot = List[Element](FilteredElementCollector(doc).OfClass(FamilySymbol).ToElements()).FindAll(filterAnnot)

OUT = symbAnnot
