How I helped create the Bridge from a fellow student

Fixed the mistake by deleting faces that connected to the bridge that it had problems with (old bridge). The next thing, was to select the border edge tool from the jaw. Only it had 6 lines rather than 5, so select the 6 border edge tool and the rest of the lines that needed to be select. That were the other 3 lines that connected the wall (the side of the helmet). Selecting all these lines, but there was a extra line that was needed to select, so I selected it. The rest was to just go to Edit Mesh and click the little cube of the Bridge. Then just click Bridge rather than Apply and it's done. The settings needed to be the Divisions: 0 and Smoothing Angle: 30.0000
