Could someone explain me why and when to use counterdimensions .Why is the "counterdimension" not simply the dimension value, given by the counterpart (on dim1 --> dim4 ) and do we need an extra dimension, named "counterdimension" for it .
(I know how to set it up, technically, only don't understand when to propose to set it up.
Thanks
