WombatDynamo: "The symbol is not active"

Packages

@DavidDK, that’s because I missed the for loop to iterate through the list of items . Try this one:

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

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

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

doc = DocumentManager.Instance.CurrentDBDocument
famtype = UnwrapElement(IN[0])

TransactionManager.Instance.EnsureInTransaction(doc)
# Make sure the familysymbol is active
for i in famtype:
	if i.IsActive == False:
		i.Activate()
		doc.Regenerate()
TransactionManager.Instance.TransactionTaskDone()
OUT = famtype
