I'm about to drop the correct answer, and you know it's right because it makes 3d artists and machinists mad.
Z is a stick that sticks out of your work. Blueprints are laid flat on tables, and art is hung on easels. The schematic Z axis points away from the center of the earth because it's laid flat. The artwork Z axis points parallel to the earth's surface because it's standing upright.

Isn't CAD also usually Zup?

You're almost there. Now consider how computer monitors are oriented.

Why are you posting an entire thread then, retard? Clearly you're leaving plenty of room for discussion.

notice how when working in 3d space you aren't exclusively looking at it in an overhead view? And that if you were, then that overhead view wouldn't be zup if it were yup? niggggggeeeeeerrrrr

What axis combination is intuitive for use in the real world?
>xy for plane and z for height
>xz for plane and y for height
everyone knows maps are xy. Everyone knows grids are xy. Everyone knows that the most commonly used axes that we use, i.e. how we walk and drive, are going to be more important, so make them x and y. And have z as the extra axis, separate. It is intuitive. It makes sense. It's already aligned with our view of the world, even across borders and oceans. It is only argued against by paper-thin quips like "hurr durr y up cus it's up on a paper" (even though it is simply used to represent the perpendicular to x, regardless of whether or not it represents height or distance)
Yeah, zup or bust.
