When moving (parts of) objects, there is currently the choice of Object Coordinates or World Coordinates. World coordinates are fine, if you are using the first plate, but if you are trying to replicate locations of parts on multiple plates, this does not work, because World Coordinates are from plate 1 outward, so any additional plates have a multiple in the value used to locate an object on that plate.
To solve this, I would like to see Plate Coordinates.
Or am I doing something wrong, or do I need to explain this better?
