Aligning surfaces to each other

Hi everyone,

I’ve been trying to figure out how to align those 6 layers perfectly - manually I can’t manage to place them exactly onto of each other (on the y- and x-axis). These surfaces are all “floating” on top of each other and need to be perfectly aligned to the black box.

Thanks so much!
Best,
April

Have you tried the Align command?
