Toolbox OEM 2025, CCL 50.3, why does perfect grain not work with a negative z value? As far as I know there is no way to get the hinge machining on the door to be at the right z value and also have perfect grain with the 3d looking correct and the door below the bottom. 

What I am also aiming to achieve is a custom elevation which consists of finished cabinet ends on each side of a 2 door base, but the whole elevation needs to be grain matched. The cabinets on each side are rotated 90 degrees. What's the best way to achieve this grain matching?
