Hail four-oh-five. I put together the video below to illustrate the practices and methods I employ when creating an unfold for a 3D model. Effective unfolds allow those assembling the paper to work quickly and efficiently. Unfolding models effectively involves more than simply specifying a scale and hitting the (not magical) unfold button in Pepakura Designer. I'm hoping to help community members that are interested in improving their unfolding skills. I neglected to mention it in the video but the best advice I can give those that are looking to improve is to practice. The video is fairly long so I suggest putting it on in the background while you work on new unfolds. If you know absolutely zero about unfolding or Pepakura Designer please visit the Tamasoft website (Pepakura Designer) to check out the program and learn its basic functions. This tutorial does not cover the very basic. If you'd like to follow along with the tutorial using the specific model I used for it, below is a link to the raw OBJ file just as it was exported from the 3D modeling software. Also below is a link to the PDO file which contains the unfold final result of the tutorial for reference. Thank you to SavedbyGraceG12 for the suggestion.

If you prefer different methods I encourage you to pursue and develop them. Disclaimer #2: This is the my first video tutorial. I'm not the greatest speaker so I hope you're able to assimilate most or at least some of the ideas presented.
