actually I try to not use lines at all in Pepakura ! Cut lines I can live with at a 1 .. but no fold lines especially! I really hate seeing a really nice model with dashed lines all over it! No matter how small and light they stick out like a sore thumb.! I would rather break the thing into more chunks than have to place folds all over it! The builder always has the option in viewer to turn on fold lines to see what he need to do.. and edge matching should be enough to build the model.. and DON'T EVEN get me started on TABS/// "We don't Need No Stinking Tabs".. I think I'll make a Signature with that one!
