You’re using a node that specifically gets the host element. Just remove `Properties.RebarHostElement` from the workflow and see what happens.

I already try to remove that nodes. The result is Empty List.

I don’t think rebar has geometry like other modeled elements. It’s a system family and doesn’t really act the same way. It does just have a parameter, Reinforcement Volume, that gives the total volume of the rebar system. You can also just calculate the volume from the cross-sectional area and bar length.

You can use the out of the box `GetParameterValueByName` node to get any of those parameter values.
