Why SideFX have chosen default XY Plane for Grid/Circle/Whatever to face in Negative Z?
I came with this question because it does not fit into my logic that calls that default created objects should face up (or have normals be directed) to scene coordinate system.
I wish someone can explain me why I'm wrong..if am I.
Thank you.

I recall in programming land that the default glm camera/opengl API the positive z-axis going through the screen towards you, maybe related to that!
That is my guess as well. When you put down a Houdini camera, it is facing in the negative z-axis. That is also the default axis when you do “look at” constraints. So by having these “flat” primitives point in the z-axis, this makes it easier to do “look at” constraints with off the bat.
