The new volume that “Crop volume” module creates has much higher resolution than the original, so you can create segmentation with smooth edges. Make sure you click on Apply in Crop volume and when you go to Segment Editor module, choose the high-resolution volume to define the segmentation geometry (see instructions [here](https://discourse.slicer.org/t/cannot-apply-threshold-on-roi/7269/2)).
