I'm trying to round the body for a helicopter I'm modeling using a side and front view, however I was wondering if there would be any easier way to do it than moving every single vertex.
Personally, I think that for this situation it would be best to round off the geometry in edit mode. Especially since you will (presumably) be modeling more details to the mesh such as windows, doors, tail, etc. you will want the mesh to be more contoured.
The way I would do this would be to use the smooth function and then tweak it a little with proportional editing.
To do this first go into edit mode and select everything, then bring up the specials menu with W and select smooth. You can tweak the smoothing by going to the bottom of the left toolbar (T) or hitting F6. I used the default smoothing value of
0.5, but increased the repeat value to
Then I would tweak the mesh around using proportional editing, turn proportional editing on with O. You can set the falloff curve in the footer of the 3D view and adjust the falloff radius with the scroll wheel. You can go into wireframe view and line up your model with the background image to help with the tweaking process.
Here is what I came up with after a little tweaking.
