Ok, so I want to create an outline-icon. Therefore I made a rectangle and chose to have my border centred, so that round corners are actually round on both sides. In order for it to be pixel-perfect, I want the border to lie on the pixels and not between them, like this:
However Sketch keeps rearranging my rectangle the way I do not want it:
Now, when I edit vector-points I can choose how sketch places these in relation to the pixel-grid:
Is there some similar option for aligning objects, rather than their anchor-points? Because this is driving me crazy. Even if I duplicate a perfectly aligned rectangle using alt/option + drag, it moves both of them to lie between pixels ...
