Controlling the `0' point

How do I control where the ‘0’ point is with regards to garments with bands?
Answer: Choose to view both Dimensions and Backed Off Dimensions(if used) in their Cumulative mode. Then, you can change the ‘0’ point to be either at the bottom of the sweater or just above the hip band, depending on where you click.

OR

Knitters can display the Row Counts, and click on a row count number to set it at '0'.
