Parameter value list to element name or element ID

Hi,

how can I convert parameter value list to element id list?
PFA


parameter list.dyn (18.5 KB)

Do you want to write the element ID as a parameter again?

Like this, you can take the data and use it as per need.

Element ID.dyn (16.8 KB)

actually I want to select that element again (filtered by Duct System Type parameter value only)
