Filter Elements Visible in View

Overview

The FilteredElementCollector class allows passing a view identifier to restrict the search to elements visible in that view.

Example

1. Get the active view and document:

   doc = DocumentManager.Instance.CurrentDBDocument
   view = doc.ActiveView.Id

2. Filter elements in the active view:

   elem_in_view = FilteredElementCollector(doc, view).OfCategory(BuiltInCategory.OST_Walls)

Note

This method does not work with elements hosted in links. Starting from Revit 2024, the following procedure is recommended:

1. Link elements visible in view:

   link = UnwrapElement(IN[1])
   elem_view_link = FilteredElementCollector(doc, view, link.Id).OfCategory(BuiltInCategory.OST_Walls)
