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.

Hi @DENIS.REMESNIK, It’s not saying set is not available, it is saying that you are passing in nulls and that’s is why set is not available. Have you debugged by outputting just the lists of dimension/text note types? You could add a small change to test if the object is null before trying to get and set it’s parameters. Cheers, Dan

I append the elements in the list and this list consist different elements which i should changes. But when i try changes this elements I get this error.

UP2. Maybe someone can advise another way to achieve the goals of this topic?

Please browse the forum and try to be more specific by refering to what has already been done: [image] Setting the builtin parameter accessible thru the family editor? Revit Following my previous post any ideas in how to accomplish this? Not available in project: [image] But available when family is edited: [image] Thanks,

Thank you for the your reply, but it’s not the same problem. I found it topic before - but in this case Konord changes the parameter of family. I want changes the parameter of elements which located in the family.

Do you mean this? [image] Change parameter values in multiple nested families Revit Dear BIMmers, Any ideas here? Please help I have multiple nested families which need to change in some 750 odd parent families. Its a standard content for a client. Example: I have A, B, C and D nested in X,Y,Z… and so on loaded in 750 families. A, B, C and D have a specific code to their type. Which I need to update in all the parent families (X,Y,Z…750 families) Any quick way to this using Dynamo or some plugin? Any help is highly appreciated Thanks… slight_smile

In my code above I found this elements inside families but I can’t changes they values.

It look like you are trying to change the font of the text?

You are right - I try change Text Font in text and dimensions!
