I just tried to export a scene using the 4.21E exporter and I am getting the following error: [TABLE]
Cannot export the active 3D view: An item with the same key has already been added. at Autodesk.Revit.DB.CustomExporter.Export(View3D view) at DatasmithRevitExporter.DatasmithRevitCommand.Execute(ExternalCommandData in_commandData, String& out_commandMessage, ElementSet out_elements)
Some help would be greatly appreciated as I am trying to get this scene into a walkthrough. Thanks!
If it helps, I tried this on another scene but that one was very basic and it worked. The scene I am trying is a developed project with lots of information and assets so I am not sure if that is impacting things.
