Well, I think it's better to work on an "unmirrored" side.
So the top side would only be mirrored when editing the bottom side. Then it would prevent inverting pins by mistake when routing the bottom side.
It looks like I'm the only one having this kind of issue
I've had bad surprises on some of my PCBs with footprints that were upside-down due to misplacing on the second layer (the green one).
I think it would be useful to be able to view this side with horizontal mirroring, just like it's already displayed in the Photoview.
I've tried to understand the answer from abacom but the online translators don't really help that much. So, can anyone tell me in english (or french) how to make oval holes with Sprint Layout please?
