Revit Link Visibility

Developers

Hi everyone,
How can I copy the settings (visibility, halftone, underlay, display settings) of a linked file from one view to another? For example, I have two Revit models, A and B, and both of them have the same linked file, Link_Test (in a real project there could be many linked files). In model A, I’ve already created a view template and configured everything. I then transferred the view template from model A to model B, but for some reason all the linked files in model B are always turned on.
How can I preserve the link settings exactly as they are in model A?

I’ve read through Can i copy RVT Link Display setting by Revit API? - Revit - Dynamo, but maybe I didn’t use the SetLinkOverrides method correctly, so I still haven’t been able to make it work.

Controlling Revit links in view template using Dynamo?

I asked this years ago and answer was that this is not available in the Revit API, let me know if it is not the case I am interested too

Yes, I will. It’s weird that the view template can’t handle that :slightly_frowning_face:

Which Revit release are you in? 2024 started to introduce tools for working with link visibility, but there are still a lot of gaps.

The class in question: Revit API 2026 Documentation

I’m in Revit 2025. Is it the SetLinkOverrides method or something else? Because I tried it, but it didn’t work. I’m not sure what went wrong

I’m not sure either as I haven’t seen what you tried. :laughing:

Hi @jacob.small , @rrvivancosWTL . I found a solution about setting the Visibility in this post:

Solved: hide/unhide RevitLinkInstance in Visibility settings - Autodesk Community

But still have to find solution for Halftone, Underlay, Display Settings as well. Do you have any ideas?

I tried GetLinkOverrides method but it returns None

I think these are known gaps in the Revit API.

Hi @jacob.small , @rrvivancosWTL
Here is the solution for Visibility and Display Settings. I believe the Halftone and Underlay are the limitations of the Revit API for now. I put the code here for anyone who needs it.

    # Collect all RevitLinkTypes from source document
    source_link_types = FilteredElementCollector(source_doc).OfClass(RevitLinkType).ToElements()

    # Store visibility status by link type name
    visibility_dict = {}
    for link_type in source_link_types:
        try:
            link_name = link_type.get_Parameter(BuiltInParameter.ALL_MODEL_TYPE_NAME).AsString()
            is_hidden = link_type.IsHidden(source_view)
            visibility_dict[link_name] = is_hidden

            continue

        for src_name, src_ogs in graphic_override_map.items():
            if src_name in link_name:
                target_view.SetLinkOverrides(link_type.Id, src_ogs)
                break

Could you adjust the visibility for walls? I was trying to do something similar to this, where I go to each link on my template and, besides turning scope boxes off, also change the walls to red (overriding whatever color they have). My first problem seems that I’m working on Revit 2023, but I can definitely move at least to 2024 for this. Any ideas are gladly apreciate
