We’ll implement ROI rotation in the new Markups ROI node. It should be available in a few months.

Note that you can create optimal oriented bounding box fully automatically, using 10-15 lines of code (see [New Segment Statistics: Oriented Bounding Box, Diameter and More](https://discourse.slicer.org/t/new-segment-statistics-oriented-bounding-box-diameter-and-more/10203)). The script could be slightly modified to create ROI from automatically rotate the ROI to have one side parallel to a specified line.

If you don’t want to do any programming, then you can rotate the volume so that the cut axes are parallel to R/A/S axis and then you don’t need to rotate the ROI.
