Can confirm! I have a Pepakura Designer license, and it is a very powerful tool.
Paper sculpture is something we touched on during week #3 of the Facilitating Creative Workshops course, and I listed (free) alternatives to Pepakura Designer in this topic if you’re curious!
I will say though, if you have the budget and you’re going to make a lot of custom paper models, Pepakura Designer is definitely worth the investment!
