Helmet Failure

In Maya, theres a tool called "Bridge." Which in the name, just connects one's edges or vertices to the other object's edges or vertices. Connecting by adding a new face or just extending the face to connect to the other side. In my Helmet Model on Maya, this did not work for me for a number of reasons, such as not much edges to have, sides to far, to wide, numbers of sides, and others I can't remember. When I do make it to work, it isn't how it should be and really doesn't look so well. I will keep on trying with trial and error.. or my good ol friend Google.
