    By your own logic there is no “up”, only x/y/z, so what’s your complaint?

    There is NO mathematical or physical reason why XY should be the floor, that is your own bias.

      No. That is not my logic. It’s the logic of Rene Descartes who invented the thing you are trying to talk about.

      And because gaslighting attempts online are hilarious, I’ll assume you just didn’t read so good and will repeat myself again; we tend to rest the plane on the floor, as it is in our reality with gravity it is easier to conceive. Like modelling a car, it’s wheels on the screen spend most of the time pointed down.

      You don’t have to. You can model it any direction you want, but most people find it easy in an orientation that mimics common perspective. But however you do it, you still can’t have a Z axis without a plane. That’s the point. Grid is plane and plane is needed for Z. If you have a grid on Z it’s representing an infinitely possible slice through extrusion and that’s basically a concept behind some fractals, which introduces a new vector for new XYZ points within.

      I know you really want to be right but this is very long-standing foundational and basic stuff we just do. It isn’t my logic or opinion, I’m sharing this knowledge to you, something you can very easily look up yourself right now and forget I even exist—which would be neat.
