Among all the functions, pockets creation can be usefull. Sometimes the printing support can be quite massive, so in order to lighten it, we use the pocket function. This function allows to create a pocket into the printing support.
Of course, it is possible to generate the pocket either for the bottom or the top support, depending on what you have created before. The pocket can be generated in 2 clicks easily when in a CAD software it would take much more time to do so.
