My awesome macropad!

Hey everyone, so we got a bit of a problem… (Check image below).
I was trying to make a hole in my PCB, and I think I inverted the whole thing?
Like it just randomly got all of these empty spaces in places where it once had material…
Unfortunately I can’t just go back since I closed FreeCAD when this happened cause I tought it was just a visual bug (Yes, I know, a very dumb decision ).
This actually happened about two weeks ago, and I kinda dropped the project when this happened, but I decide that I want to finish this HackPad!
If there’s really nothing I can do to fix this then I guess I’ll just redesign it from the ground up, but that would take quite a lot so I’d really prefer it if someone could help me with this in the comments.

Lost a whole hour of recording cause I accidentally closed the window, AND I’m stuck on the case, cause I just can’t fit the case generated from ai03’s case generator to fit.

So I’m very close to finishing the Case for the YummyPad, but I’m stuck at one part, I’m trying to extrude the piece you see in the photo (Inside of it are the knob and the OLED screen), but when I try to extrude it it just deletes evgerything and only extrudes the circle, lol (Not very funny working with it but whatever), I’m SO close to finishing this and just need this last step to work out!!!

Added an OLED screen and a Rotary Encoder (for controlling volume/brightness)

Just finished the first part of the HackPad tutorial (KiCad)
