I also would like to perform 3D cropping on volume rendering. Are there any current examples using Python scripted modules that I can study to accomplish this? Thanks in advance.

You can find examples of using Segment Editor effects from Python in the [script repository](https://slicer.readthedocs.io/en/latest/developer_guide/script_repository.html#segmentations) and here is an [example of using Mask volume effect from a Python script](https://github.com/lassoan/SlicerSegmentEditorExtraEffects/blob/master/SegmentEditorSplitVolume/SegmentEditorSplitVolumeLib/SegmentEditorEffect.py#L129-L192).
