Brad, When you refer to "flipping" boards, are you actually mean *mirroring* the contents of PCB files (including their components) at the time? If you're not aware of it, something to watch out for, when doing that, is that the locations of components' Designator and Comment strings can change *relative* to the locations of their parent components. This *doesn't* happen to any Designator or Comment string which has a Manual value for its AutoPosition property, but it *can* happen to any such string which has a *different* value for that property. I infer that that outcome is happening because components *don't* have a Mirrored property, so in the subsequent absence of "awareness" that its parent component has actually been mirrored, the location of such a string can change if the code controlling its location assesses that its previous location is incorrect. I first suggested that components acquire a Mirrored property many years ago, but I gather that Nick (Martin) has never been convinced of the merits of providing that property. IMO, this behaviour (of Designator and Comment strings) is yet another reason why that property should be provided (but I still wouldn't recommend that anyone try holding their breath waiting for it to be implemented). I've spoken about the matter of providing that property in other previous messages, so I'll confine repetition of previous observations to saying that while its provision wouldn't make the design of PCB files "bullet proof" in any way, it would still result in an improved outcome (relative to the status quo) whenever users ensured that any PCB file in its "initial" state incorporated no components in a mirrored state (nor subsequently "acquired" any components in a mirrored state). (In other words, users still need to ensure that all footprints are correctly defined within PCB Library files in the first place, and within any "legacy" PCB files, etc.) Regards, Geoff Harland.
