Fillet edge on solid

I am modeling a mouse and cannot fillet edge between upper and lower halves? the edge will not select. What can I do and how can I post the file? Thanks

If you can’t select the edge, it may not be joined to anything else… For FilletEdge to work, you need a joined edge. Otherwise, you might want to try FilletSrf…

To post a file here, either use the little cloud-arrow button at the top of the post window, or just drag and drop the file into your post.
