Placing Attached Detail Groups for many Model Groups in many views

Revit
, ,
1

I’ve been trying to make a script which will turn on many detail groups from several model groups in a series of views. I have everything up to the very final step which I cannot figure out. I’ve found several topics on here and tried the nodes/code but to no avail. I’ve tried doing it with chatGPT and also asked it to modify the other examples but nothing I got would work for me.

Below is the last portion of my script where I have lists for all views, all groups and all detail groups. I’ve also attached the script although it might be slightly specific and not work?

Anyone who can wrap it all togther and turn on the attached detail groups?

I had a little time this afternoon, togther with chatGPT I managed to figure this out, code below

# --- Import Revit and Dynamo API dependencies ---
import clr
import sys

# Add .NET assembly references for Revit API access via pythonnet
clr.AddReference("RevitAPI")
clr.AddReference("RevitNodes")
clr.AddReference("RevitServices")

# --- Revit API Imports ---
import Autodesk
from Autodesk.Revit.DB import *

# --- Dynamo Revit Wrappers ---
import Revit
clr.ImportExtensions(Revit.Elements)  # Enables UnwrapElement() and other helpers

# --- Dynamo Revit Services ---
import RevitServices
from RevitServices.Persistence import DocumentManager
from RevitServices.Transactions import TransactionManager


# --- INPUTS ---
# IN[0] -> list of lists of model groups (each sublist corresponds to a view)
# IN[1] -> list of lists of lists of detail groups (sublist per model group, per view)
# IN[2] -> list of views (one per outer list)
modelGroups = UnwrapElement(IN[0])
detailGroups = UnwrapElement(IN[1])
views = UnwrapElement(IN[2])


# --- DOCUMENT REFERENCE ---
doc = DocumentManager.Instance.CurrentDBDocument


# --- START TRANSACTION ---
TransactionManager.Instance.EnsureInTransaction(doc)


# --- SAFETY CHECK ---
# Ensure all inputs are present and non-empty
if not (modelGroups and detailGroups and views):
    OUT = "One or more inputs are empty or invalid."
else:
    # --- MAIN LOGIC LOOP ---
    # Iterate through each view with its corresponding model groups and detail groups
    for v, modelList, detailLevelList in zip(views, modelGroups, detailGroups):

        # Iterate through each model group and its corresponding list of detail groups
        for m, detailSubList in zip(modelList, detailLevelList):

            # Iterate through each individual detail group for this model group
            for d in detailSubList:

                # Show the attached detail group in the specified view
                m.ShowAttachedDetailGroups(v, d.Id)


# --- END TRANSACTION ---
TransactionManager.Instance.TransactionTaskDone()


# --- OUTPUT ---
# Return the original model groups back to Dynamo for reference
OUT = IN[0]

Does anyone know how I might access the parmeter “Allowed View Types”?

I can find something about BuiltInParameter Enumeration and GROUP_ALLOWED_VIEW_TYPES but I’’m not sure what to do with this and it was for Revit 2026.
