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.

There are cases where even the Join/Disjoin feature can't break down the pieces any smaller to fit a page. As you have seen yourself, rifle barrels tend to fall in that category. In which case, you have no choice but lay it out and let the piece occupy two or more pages. Of course during the cutting process, you might encounter a problem of re-aligning the pieces. To avoid or minimize this problem, make sure that you go to Settings --> Print and Paper Settings and check the box that says "Print Alignment Marks for Multiple Pages." Then, insert a picture (any picture) on the piece, making sure that the dotted line on the 2D Development page passes through that picture.That way, when you cut the pieces, you can easily re-align them together upon assembly.
Press the PrintScreen key on your keyboard and then paste it on your favorite photo editing software.
Make sure you install Pepakura Designer in your computer. Then right-button click a pep file and select Properties. On the panel that says Open with...", click on "Change" and browse for Pep Designer. Then click OK.

I suggest that your time is best spent reading all the threads labeled as "sticky" in the Pepakura and Cardboard Armor forum. You will find your answers there, starting with the Ultimate Pepakura FAQ.
Well, that's the price of using HD pep files.

They serve as details that you add to the helmet later on. On my helmet build, I glued these floating faces on a foam sheet and then cut them out. I then glued these pieces to the helmet.
