Get Parameter Value of Elements in Linked RVT

Hi @Lam_Hung,

The first 3 nodes in my picture will get you the linked elements, of the chosen category.
Than you can do some filtering to select only the elements you want.
As the last step you can replace the Element.Parameters node by the one in your picture.

As mentioned before, if you want to code it in Python (i can’t help you) but you could rightclick the first 2 nodes to check what Python code is inside.

Kind regards,
Mark
