Hello everyone! I try changes parameter Text Font from elements into families, but i have a trouble, please help me find solution! Script find elements but can’t changes the values because method Set is not available. This is my code and screenshot: import clr clr.AddReference("RevitNodes") import Revit clr.ImportExtensions(Revit.Elements) # Import DocumentManager and TransactionManager clr.AddReference("RevitServices") import RevitServices from RevitServices.Persistence import DocumentManager from RevitServices.Transactions import TransactionManager doc = DocumentManager.Instance.CurrentDBDocument # Import RevitAPI clr.AddReference("RevitAPI") import Autodesk from Autodesk.Revit.DB import * import System import sys pyt_path = r'C:\Program Files (x86)\IronPython 2.7\Lib' sys.path.append(pyt_path) NameOfType = IN[0] errorReport = None output = None try: def setWhatYouNeed(d, s): TransactionManager.Instance.ForceCloseTransaction() familyDoc = doc.EditFamily(s) TextNotesType = FilteredElementCollector(familyDoc).OfClass(TextNoteType).ToElements() DimensionsType = FilteredElementCollector(familyDoc).OfClass(DimensionType).ToElements() TransactionManager.Instance.EnsureInTransaction(familyDoc) for list in [DimensionsType,TextNotesType]: for element in list: element.LookupParameter("Text Font").Set(IN[0]) TransactionManager.Instance.TransactionTaskDone() for symbol in IN[1]: setWhatYouNeed(UnwrapElement(symbol).Symbol.Family.Document, UnwrapElement(symbol).Symbol.Family) except: import traceback errorReport = traceback.format_exc() if errorReport == None: OUT = output else: OUT = errorReport [image]`

Here is a slightly cleaner version of the above sticking to mostly what is in the box. Slight cleanup on the code also and using the get_Parameter(BuiltInParameter.TEXT_FONT) like my earlier post rather than a string search as @til.shviger flagged up in a separate post will cause errors in different languages should you want to distribute it. Output data is a little more descriptive too, so you can see what ElementTypes were updated in the family for each family. Run input added if you want to keep it and a doc.refresh to tie it all off.

@Daniel_Woodcock1, could a minor modification be implemented to be able to change fonts in nested families?
