Note for interpreting the message above: SE = Segment Editor

There are many ways to create “smoother” cuts:

- You can create straight cut edges if you select circle or rectangle mode in Scissors effect.
- You can apply [local smoothing](https://discourse.slicer.org/t/new-segment-editing-feature-smoothing-brush/14577) (e.g., opening with kernel size of 3mm).
- You can create a cutout shape using Baffle Planner module (in SlicerHeart extension) and then use that shape to cut out from the model using Combine models module (in Sandbox extension).
- You can use Dynamic Modeler module’s “ROI Cut” tool to cut straight edges with a resizable, rotatable, rectangular ROI

Do you have any specific concern (anticipating issues with sterilization, difficulty 3D printing…) or just aesthetics? Is there any requirement that you would like to fulfill?
