Modify LinkVisibity with Dynamo

Revit

Hi everyone,

I’m trying to do a script to modify link file’s visibility with Dynamo. I saw with the new API in Revit 2024 that it’s possible ?
I try first with Rhythm package but I got blocked, so I try to do a python script with the new Revit class for LinkVisibility but I don’t know how to match the argument for View.GetLinkOverrides…

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

clr.AddReference('System')
from System.Collections.Generic import List

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

doc = DocumentManager.Instance.CurrentDBDocument
uidoc = DocumentManager.Instance.CurrentUIApplication.ActiveUIDocument

linkinstance = IN[0]

ViewType = []

for Views in linkinstance :
    ViewType.append(View.GetLinkOverrides(Views))

OUT =  linkinstance

Hi @guillaume.trang ,

Could you share the API Page where you found that it’s possible in Revit 2024 to change the link visibiliy?

Yes of course !

Hi,

it seems for now it’s limited to defining a linked view.
here an example to set a Linked View

Hi,

Thanks for your reply.
It is what I try to do, so I ran your python script but I got this error…
And when I click to continue, I don’t have anything in the second selection

Capture

I’m not with PC but for a CPython3 compatibility you need to cast the list ‘self._lstLinkViews’ into a .Net ‘List[DB.Element]’

I will update the code later if necessary

Hi,
code update for all PythonEngines in previous my post
