Trying to join two closed solid polysurfaces with a fillet

I am trying to join these two closed solid polysurfaces together with a fillet, but I am not having any luck.
Does anyone have any suggestions.

Hi -

I only see one object in that screenshot. Could you post the 3dm file and possibly describe the procedure that you are not having any luck with?

Thanks for the quick reply. It is actually two objects the hollow cylinder and a hook that I am trying to connect with a fillet (full disclosure fillet may be the wrong word I want a rounded edge where the two connect).I have attached my file below.

Hi - a simple BooleanUnion followed by FilletEdgewith radius .02 seems to work fine.
