Alignment of surfaces to a curve (loop) or vertex...? New to Blender...great program.  Coming from the Rhino nurbs world. 

Going through a Blender Guru tutorial on making an anvil.  

Have a question...how do you center a series of faces to a centered "loop" or align the faces to a center "vertex"?  

Screen shots attached.

Thanks,

It looks, in this case, as if you should just be able to set your snap to 'Vertex' and 'Active'... select the vertex at the peak last, (so it's the active one) and GY the lot,  hovering over one of the vertices on the central vertical loop to induce the snap.

Either switch on 'Automatically Merge Vertices' in the header before the move, or CtrlVR.. Remove Doubles when you're done.
