It is strongly recommended that you don't attempt to edit Origami files by hand, as it can be very hard to identify exactly what the individual numbers mean. To change folds or orients read them back into PRIMER and edit them there.
Also, try not to separate Origami definitions from their parent input decks: they reference SET and other entities within these decks, and confusion will arise if these labels are not treated consistently.
