Hello georgepaul, I have been using TreeMaker for a long time, and it isn't useful for diagramming. That's more beneficial for generating CP's. If you're searching for software that would not only give you a crease pattern but also a step by step diagram of the model, I would recommend that you give ORIPA a try. While it may have a few glitches to get working on a 64-bit version of windows, it does work really well and provides the desired result.
