As the name implies, it would allow you to manipulate the build box. For example, say a large core is 128x128x128 and you just wanted something a bit longer but just a fraction of that width. Allows to subtract from unused axis to add to desired one. Keeping the same total build volume and game balance of various sizes cores. I don't know about y'all, but most ships I want to build are alot longer than they are wide or tall. This is something I brought up in game, but thought it appropriate to bring to the forums.
