Go to 2D Menu --> Edit Mode --> Join/Disjoin Face. Then move the cursor over the piece in question until a green line appears. Double-click and then the piece will be cut along that line. You are then free to move the pieces to another part of the 2D Development page.I wanna work on my first full suit of armor (for a year I've been doing nothing but pieces), and I need to know how to scale them in pepakura designer so they come out larger when they're printed, but when I scale them up, they go off the paper, and that makes it very hard for me to work with. What do other people do when this happens, because I know that I'm not the only one that this happens to, or do people just deal with it? If so, how?
