WILL IT STAY LINKED IF I CHANGE THE MODEL? - If the dimension exists it should stay linked.
ALSO CAN I LINK ONE DIM INTO ANOTHER..... SAY I WANT TO DO 4X 4.00 = 16.00 NON-CUM.... THE REAL DIM IS 16.00 BUT I WANT TO MAKE THE 4.00 LINK ABLE.. - not sure what the situation is so I can't comment specifically, however maybe it's an equation you are looking for? possibly trying to use a variable to drive dims?
