Add Shared Parameters from txt File Error

Hi everyone,
I am trying to load shared parameter to the project and then bind them to the categories

# Import the required Revit API classes
import clr
clr.AddReference('RevitAPI')
import Autodesk.Revit.DB as DB

clr.AddReference('RevitNodes')
import Revit
clr.ImportExtensions(Revit.Elements)

# Set the path to the shared parameters file
sharedParametersFile = IN[0]

# Load the shared parameters file
defFile = DB.ExternalFileUtils.ToString(sharedParametersFile)
categorySet = DB.ElementIdSet()
categorySet.Insert(DB.ElementId(DB.BuiltInCategory.OST_Walls))

# Create a category set and a definition map
categorySet = DB.ElementIdSet()
categorySet.Insert(DB.ElementId(DB.BuiltInCategory.OST_Walls))
defMap = DB.DefinitionBindingMap()

# Add the shared parameters to the definition map
for defGroup in defFile:
    for definition in defGroup.Definitions:
        if definition.Name not in defMap:
            defMap.Add(definition, categorySet)

# Bind the shared parameters to the categories
doc = Revit.ActiveUIDocument.Document
transaction = DB.Transaction(doc, "Bind Shared Parameters")
transaction.Start()
DB.ParameterBindingService.GetBindingOptions(doc)
DB.ParameterBindingService.OverrideBinding(doc, defMap, DB.BindingPriorityType.Temporary)
transaction.Commit()

Something doesnt seem to work. Could someone help me understand where might be going wrong about the steps.

Your code?
There are a bunch of issues.
First you need imports. You can’t declare DB unless you have DB.

import Autodesk 
from Autodesk.Revit.DB import *
from Autodesk.Revit.UI import *

Further, it looks like you want to work with system collections. Need to import those first.

from System.Collections.Generic import

Next, your declaration of a collection isn’t quite right. There is no thing called an ElementIdSet. You can make a Element set. Or you can make an ElementId set. Really those are iList collections.

categoryIdcolelction = List[ElementId]()
elementcollection = List[Element]()

Then to add to the List (these are .Net Colelctions - not python lists…), just use elementcollection.Add(eleement), rather than elementcollection.Insert(element)

There is a ElementSet class in DB. Are you trying to use that?

categorySet = DB.ElementSet()

But I’m not sure that is what you want. ElementSet is usually used for a document selection or FiltereElementCollection and can contain elements of different types. Here you are after a strongly typed list. But ElementSet would tie in with your Insert() method as that is indeed a method of ElementSet…

I hope that gets you pointed in the right direction. Not sure how you derived the above code unless you were just copy/pasting stuff(?)
