Hello, I am a new user of 3Dslicer on Mac, version 5.2.1.  
Do you know if it is possible to display a landmark line to match the sagittal and axial views on a lumbar spine MRI? Can this line have an editable angle?  
I am able to model the sagittal and coronal views from a 3D DICOM axial MRI, but can’t see where I am on the different slices and views.  
Thanks

Maybe the Slice Intersection feature is what you need. You can enable them with the toolbar and then click and drag with left mouse for translation, or control-alt-left-click and drag to rotate.
