Change element workset using get element by system classification or system type

Hello all, I am new to Dynamo and I need quick help.

I wanna resign some already modeled elements (in this case, Pipes) from on workset to another. The best way to get the exact pipe is using system-type or classification as a parameter before asking dynamo to reassign them another workset. Thanks for your suggestions :slight_smile:

What is your question? What have you attempted so far? We need more information to be able to help you. Have you researched filtering system families or worksets yet?
