I want to get a PCB made by dirtyPCBs, which has a great price for boards, as long as it fits in a standard size. For example, 10 copies of a 5cm X 5cm board is only $14.
I'm using KiCad to lay out my board, and want to start with a 5cm x 5cm board boundary (edge cuts) so I know what I'm working with and can tell when I start to use up the available space.
What's the most straightforward way to get a rectangle in KiCad that's precisely 5cm x 5cm?
I don't believe there's a rectangle tool, so I'm happy to make it out of four separate lines; but I'm having trouble working out how to get make something 5cm long, perhaps by entering it in a dialog box or something rather than counting little grid dots :)
Is there a straightforward way to accomplish this?
