Push/Pull a circle from a rectangle

Geo, I was going to ask "How do you get the transition to be symmetrical? Try as I might, I always get the following: "

But your comment about the cardinal points means I need to rotate the circle so the circle’s edge is parallel to the sqaure’s edge. It’s odd SketchUp does not create a nice symmetrical transition when creating the geometry in the more natural SketchUp way (without rotating the circle.)
