I am now trying to read source code to learn but I have no idea to find the exact file or location for the method I am interested in at this moment. Can anyone help?

Here you go: https://github.com/Slicer/Slicer/blob/0e332ecdadff2034071260e8ffb5dd38e8f1ab42/Modules/Loadable/Segmentations/EditorEffects/Python/SegmentEditorMarginEffect.py#L13

I searched “margin” on the Slicer github repository and looked through the first few code results. I knew I was looking for a Segment Editor Effect, which helped.

There is also this example in the script repository which uses a VTK filter directly (though note that the margin is specified as a kernel size is in voxels rather than millimeters in that case).Script repository — 3D Slicer documentation
