How to provide global coordinate system after crop volume segment?

Export segments to model nodes (using Segmentations module, Export/import section) and apply transform to a model (using Transforms module) to move it around. Either use sliders to change the transform or enable Interaction/Visible in 3D view to move it interactively in 3D.

If you see that first two axes of the exported model are inverted the apply a diag(-1,-1,1,1) transformation matrix on the models before you export.
