Hello,
What is the supported method for changing a diffraction grating’s direction? By default, the grating is ruled in the x direction. I would like to change it to the y direction. I have tried surrounding the grating by a coordinate break of 90 degrees about z, but this did not change the orientation of the diffracted light. I have also tried using 90deg rotation about z in the tilt/decenter menu to no effect.
Thanks!
It appears that the grating direction was rotating after all. The coordinates in the 3D layout also rotated, so it appeared that the direction was still along x. When I create two gratings in the same model and rotate one but not the other, the directions are perpendicular as expected.
