Okay, am I understanding this correctly? In Y-up right-hand, positive X is "to the left"?

I personally think that right-hand Z-up makes the most sense, but it makes sense to move to where most of the industry is going.

No, the x-axis is usually the only consistent one (it increases from left to right). With right handed coordinate systems you can have Z going into the screen (Y-down) or Z coming out of the screen (Y-up)

That makes more sense. Simple explanation of my error. Thank you.
