Hi, I guess you can do the following:

To duplicate a **segment** you can Add a new segment and use the Copy operation under the Logical operations Effect.

To duplicate a **segmentation** you can clone the node by right clicking → Clone in the Data module

@simonoxen  
Could you please tell where to find “clone” segment file to explore its functionalities (i.e. .cxx or .py file)?

This question has just been asked and answered here, too:

I’ve submitted a pull request that makes “Clone” action clone the segment if the user right-clicks on a segment (and not clone the entire segmentation):

> <https://github.com/Slicer/Slicer/pull/5700>
>
> Previously, "Clone" action duplicated the entire segmentation node, even when ri…ght-clicked on a segment.
> This commit changes the behavior so that if the user right-clicks on a Segment and chooses Clone then only that selected segment will be cloned.

It will be probably merged within 1-2 days and appear in Slicer Preview Release the next day.
