How do I use CTRL-R to cut all the way through an object, not just one face? Can you please tell me if there is a handy shortcut or hotkey using CtrlR or the knife tool to cut ALL the way through an object and not just it's face? I want to make a simple cut to make the tape follow the form of the bottle.
The knife tool will work in this situation. After pressing K, hit Z, which will put it in cut through mode.
