This isn't so much a PADS question, more layout in general. I'm adding various power planes, some go thru the board on all layers, some do not. For the ones that go thru the board, is it better practice to make all the edges line up or is is better to offset them slightly. If they are lined up, it's a lot cleaner looking, but I'm wondering it there is any mechanical reasons to offset them. Hopefully this makes sense. Any thoughts?
