hi @robert12546358,

try this: change_assembly_name.dyn (7.9 KB)
just change the second Category to any category you want but it should exist in your assemblies.

it should look like this:

python script:

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

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


doc = DocumentManager.Instance.CurrentDBDocument
TransactionManager.Instance.EnsureInTransaction(doc)

elements = UnwrapElement(IN[0])
for el in elements:
	param = el.LookupParameter(IN[2])
	param.Set(UnwrapElement(IN[1]).Id)

TransactionManager.Instance.TransactionTaskDone()

OUT = elements

cheers!
