By HyperSizer convention, the x-axis runs in the "a" direction, and the y-axis runs in the "b" direction. The zero stiffeners therefore run in the "a" direction as well.

So an orthogrid pocket that has S0 = 10 inches and S90 = 2 inches is long in the

I've attached the HyperSizer image of an orthogrid panel, and I've added a quick note showing where "a" and "b" are defined. Hopefully this clears things up! I think what you described is indeed the reverse of this.

**y-axis (b) direction**because the space between 0 stiffeners is larger than S90.I've attached the HyperSizer image of an orthogrid panel, and I've added a quick note showing where "a" and "b" are defined. Hopefully this clears things up! I think what you described is indeed the reverse of this.
