I tried the alignment tool but I think I am missing something important for how to make it do what I need. Not sure if it matters but each “piece” of the plane is in its own folder.
Is it possible that Replace Face will do the trick for you? I know it will make the components a bit thicker, but refitting the cutouts could be faster this time
I think that is fine although I was really hoping for a translation along an axis and not an additive or subtractive solution.
I did go through and select all the faces to “replace face” and for some reason, I don’t have a done button. I will go back and do it piece meal and see if that works.
