So what exactly is it? Think of it as a paper doll that you can dress up in 3D space but the doll is a weird blob version of yourself and the paper clothing is a scalable pattern or model of the costume you want to make. This is one of the things that I recommend highly to anyone who even wants to step near a Pepakura pattern or a 3D printer just because of it's ease of use and the value that it adds in time saving and peace of mind when building. Armorsmith Designer is one of those tools that has worked it's way so deeply into my standard workflow that I don't really start any project without at least booting the software up.
