Hi, I have this model where I’ve done something that has messed the shading up (I assume I accidentally pressed a shortcut). The model is intended to have flat shading, and the image is with flat shading on. I can’t see any duplicate geometry and the face orientations look okay. I can undo this in my real model, but I’d like to understand what has happened here. The blend file is attached.

Hi Stan, thanks very much this sorts the problem. 
Any idea how I did this in the first place?
Thanks,
Pete.
Probably hit one of the options in the Mesh -> Normals menu by accident.
There’s not many shortcuts under that menu - there are only ones for recalculate normals and for point to target but I tried them and they have a different result. From the other options I think I must have somehow done normals merge as that ends up the same result, but no idea how I did that as it doesn’t have a shortcut. I’ll put it down to user incompetence
Thanks, Pete.
Yes, that’s true for shortcuts that are accessible without the menu. But the menus themselves (all menus) are full of shortcuts. If you open a menu and hit 1 through 9 you activate corresponding menu item in order. Or, you could hit a key that’s underlined for the menu item and activate it that way. So you could’ve, hypothetically, open the normals menu via its shortcut and then accidentally hit one of those keys.
Oooh… I didn’t realise you could access menu options with shortcuts like that.
Thanks!
Pete.
