How to create a split embroidery design

I have been working with MasterWorks II for a couple of years. I have seen how many people are creating designs that are split and names are put in the middle. I'm not sure how this is done, is it a digitizing technique or is it done in with already digitized designs? If someone could please help me with this that would be GREAT:)!!

I am not sure about master works. I use Generations and would split with divide wit a line pull the top and bottom apart and add a line to the piece that is missing one ( when u divide w a line the line will be attached to either piece when you move half of the letter. Make sense?
