Attached is my file for a simple centerpiece for a kitchen table. I always create items in Rhino so my wife can see it before I make it. However, I also try to make it as real to the output as possible, so this model has 4 sides and a bottom. Question: How do I fillet a 1/4" on all the top edges (1/4" outside edge and 1/8" inside edges) without having the anomalies at the corners? In other words, if this were one piece all the way around, the fillet command would be perfect. But since it is 4 pieces, the corners will not look real. Imagine if I ran a round-over router bit all the way around the outside edges and how that would look. I’ve never been able to figure this out.
would not be able to do that with a router the inner most corner has to fill to make a round, a router will not do this. it’ll just “miss” there and you’ll likely need to do a little hand sanding.
it would however, likely round the outer corner as you have drawn here. I was being a bit lazy.
