Revit Family Rename in a project

问题

Is it possible to rename families in a project through the API. We are recently updating and standardizing our family naming convention. I'd like to build an add-in that would rename the families in existing project to the new standard names. I haven't had any success finding an example of this online.

I’ve successfully been able to find all the family names, however, I can’t rename the family.

I’m using the C#.

I tried the direct way with .Name property and seems to work.

UIApplication uiapp = commandData.Application;
UIDocument uidoc = uiapp.ActiveUIDocument;
Application app = uiapp.Application;
Document doc = uidoc.Document;

foreach(ElementId id in uidoc.Selection.GetElementIds())
{
  FamilyInstance famInstance = doc.GetElement(id) as FamilyInstance;
  if (famInstance == null) continue; //skip element

  famInstance.Symbol.Name = famInstance.Symbol.Name + " - Changed";
}

This is what I used

Element ff = doc2.GetElement({insert family id here});

var bar = (from x in familycollection where x.Name == ff.LookupParameter("Family Name").AsString() select x).FirstOrDefault();

exEvent.Raise()
