Applied for:- QXP 2019 only.
How it works:-
On the measurement palette, you can select any of 9-reference points as indicated
Once you set a Box Reference Point, all boxes in that particular layout will work with respect to the selected reference point. On creating a new project, the reference point will be reset to the 'Top Left'.
Previously, when you rotated any object either manually or by using a mouse, the object rotated from the center. In QuarkXPress 2019, the box will rotate from the selected Box Reference Point.
