While I may still be pretty new to maya, I have spent a decently long time up and perfecting a model. Foolishly, after smoothing my model once, I deleted half of the faces, when at the time, I did not realize I had changed some of the vertices x values. Now I cannot seem to be able to move them all back to 0 x without moving one at a time.

I tried fooling around with the abs tool, but it will moves all points to 0 x but on y and z it goes to the pivot point. Much help would be appreciated.
