Skin corners: To round or not to round?

Looking through a variety of build logs, I see some builders round the corners of their sheet metal skins, particularly ones that overlap other skins, with a significant radius. Others simply debur but leave the corners square. I failed to find any guidance from Vans in the construction manual about which way is correct. Maybe I didn't look closely enough. Is the choice to round skin corners merely cosmetic, or is there a good structural reason to do it? Or is this a religious war that I dare not start?

I very rarely leave completely square corners on any part, especially sheet metal panels, if for no other reason that they snag things - clothing, rags, hands..... If you can’t run your hand over it without fearing impalement or a cut, You should round it off or debur it some more.

How much? It’s an art!

Mike,

Please consider this a plea for an upload. Always interested in basic blocking and tackling. Seems pretty basic to me, but if there's a correct method, it means that there's also an incorrect method.

Always looking to learn.

OK,

This is one technique, many others are available, but it does give consistent radiused corners. The thing is you start where you normally finish, if that makes sense...

That technique works fine for larger ones, too.
