Modelling Round Curved Edges I'm trying to make rounded off inner edges on a mesh. But I'n not on the right track, (I'm avoiding to use the Boolean.) I'm trying to achieve it using correct geometry. It does look a little bit decent, but that's after bumping up the viewport subdivision,and I've added way too many loop cuts. What would be the best modelling approach?

Thank you.
What about such topology? All quads.
