Nope. You can ONLY resize stuff in designer. You really don't even need pepakura viewer to make armor. Designer is mostly used.

So you can get rid of viewer and get designer instead.

You CAN resize the armor in pepakura designer 3. At the top, click on 2D Menu, then click on change scale. Then you just gotta figure if you measured for height, width or depth.

When I scale, I measure myself, convert it to millimeters and depending on what I scaled for, I then put that number in the appropriate box and the rest of the numbers change automatically to follow suit so that it stays proportioned.
