  • Elements outside the active section box will not be returned in the list of elements obtained from [!:Autodesk::Revit::DB::FilteredElementCollector] when this view is passed when contructing the collector.
  • Elements clipped by the active section box will return clipped geometry from GeometryOptions when this view is included in the options.
Exceptions

InvalidOperationException Returns true if the view is not a view template.
Example
C#
Copy
private void DisableSectionBox(View3D view3d)
{
    if (!view3d.IsSectionBoxActive)
    {
        TaskDialog.Show("Revit", "The section box for View3D isn't active.");
        return;
    }

    // Disable the section box (requires an open transaction)
    view3d.IsSectionBoxActive = false;
}
