I've recently played with cameras and world space etc. This is test code to get familiar with object orientation.

As you can see, I draw world axes as Line3D (comes out as right-handed with z_up, as expected). Then, I place boxes with enlarged z size. The initial orientation of the boxes seems to be different than world space orientation, though (large dimension is in world y).
Looking into BoxMesh.cs, I see lines like new VertexPosition3DColor(new Vector3D(x1, z1, y2), color) - which makes me believe that the box creation might intentionally be switching y and z. Any reason for that, I wonder?

Code:

LookAtCamera lac = new LookAtCamera(Resolve<Device>(), Resolve<Window>());
lac.Position = new Vector3D(-5, -5, 5);
lac.Target = new Vector3D(0, 0, 0);

new Line3D(new Vector3D(0, 0, 0), new Vector3D(5, 0, 0), Color.Red);   // World X
new Line3D(new Vector3D(0, 0, 0), new Vector3D(0, 5, 0), Color.Green); // World Y
new Line3D(new Vector3D(0, 0, 0), new Vector3D(0, 0, 5), Color.Blue);  // World Z

for (int x = 0; x < 3; x++)
for (int y = 0; y < 2; y++)
{
   Box b = new Box(new Vector3D(1,1,2), Color.Blue); // Should be enlarged in Z-Axis
   b.Position = new Vector3D(x * 5, y * 5, 0);
   b.Orientation = Quaternion.Identity;
}
