Help with fillet breps

I am trying to fillet the breps here but they are not working? I used dispatch to remove internal edges i didnot want to fillet…. in was able to fillet each brep individually but want to create a system where multiple breps could be fillet automatically so the steps dont get repeated

If you want to filter edges the way you started, you need to use the edges output of Brep deconstruct instead of Brep Edges.
