Ugh, when I have to open CAD for a project at work I have to setup a new coordinate system with Z going up, every time. The engineers just work with Y up for some reason. Too lazy to change it perhaps? Solid works and Inventor default Y up? I’ll never understand it. I definitely understand this meme. There’s also models with an origin 10 feet off in X and 20 feet out in Y. I just do not friggin get it man.
CAD used to be digital abstraction of the physical media that is 2D drawings on paper, so XY is the plane of the paper going horizontal/vertical, and most detailing are in vertical cross sections so Y ended up being up most of the time.
The Z axis is then Frankensteined into the existing system to get a proper 3D representation, so it became the depth axis for the existing XY plane.
In Minecraft it’s even more evident as Notch Frankensteined the Z axis into a game engine that’s originally developed for side scrolling.

Because math works with Y up. Physics steal from math, engeneering steals from physics, so, here you are.
What I can’t get is imperial measurement system. Apparently, nobody but americans can. And that stuff is far worse than Y and Z switching places.
as a minecraft player learning how to use autocad, i thought y up was alot more ubiquitous then it apparently is
That’s what I don’t get. Why would they make Z up when in algebra, Y is up. It’s all based on math, shouldn’t we keep consistent on that?
