What would you like the bounding box to do?
Would you like to fill a box shaped region with a segment?

Thank you for the response.
Yes, I would like to segment using a box(cuboid). And, I would like to export the box information in either json or fav formats.

You can place an annotation ROI (select ROI on the [annotation toolbar](https://www.slicer.org/wiki/Documentation/Nightly/Modules/Annotations) and click in the image at the center and corner of the intended box). Then you can save the annotation as a .csv file (menu: File / Save) or [write directly to a json file using this code snippet](https://www.slicer.org/wiki/Documentation/Nightly/ScriptRepository#Write_annotation_ROI_to_JSON_file).
