Duplication from linked file

how do i get duplication of elements from linked revit models??

Could you show values for this node:

PerformanceAdvisorRule.Execute node currently works for open document. For link docs or other non open docs you need to create python or C# using ExecuteAllRules Method. Checkout RevitAPI Docs http://www.revitapidocs.com/2018.1/39024ba7-f6c7-7bc3-72ee-80da074f1416.htm

Thanks for your help,:grinning:
