Sorry, I wasn't clear enough: I also mean the position of corners/frames/drafting items. Width and/or gap both together translate to position or "design resolution". I don't know how you want to call that. But the important part to me is: Please don't hard-code it. Make it adjustable (i.e. 0.05mm, 0.025, 0.01mm, ...) as it might vary how small the stuff gets. (Others might do Chip-on-Board stuff or Die-Bonding.)
