nope I cut & weld, probably not very well though, "unfold" just gives me a big mess, which I found out the first time I pressed it, never again. Normally I section off the helmet into equal parts and then work my way around making those parts smaller to fit on pages n cut them down. Afterwards I open pep viewer to check pieces quicker than that of designer, establish where I've gone wrong re-fold then recut. Once it's close as possible it's just a matter of joining and separating certain pieces In the 2D lay plan. Ill go over it again tonight.
