Hi, would request help on the segmentation of the heart. I am able to segment 3d of heart. Now I am trying to create “cut planes” and see inside of heart. How can I do that. Would appreciate the help.  
Thanks`

You can use Segment Editor module’s Scissors effect. You may find this [craniotomy example](https://lassoan.github.io/SlicerSegmentationRecipes/Craniotomy/) helpful.
