how do use FET to define feature

Hi FL_10688466,

Welcome to the PTC Community!

Thank you for your question.

I’d like to recommend to bring more details and context to your initial inquiry.

It also helps to have screenshot(s) to better understand what you are trying to do in your process. This will increase your chances to receive meaningful help from other Community members.

You could start by using the wfcWFeature method `GetElementTree` to extract the FET from a feature you already have, then you will be able to see how a FET is structured and recreate that
