When you press the "3" key on maya with an object selected it will smooth the object pretty much "merging" all the faces to look like one, even curving the edges. Is there an option like this in Blender I've tried Smooth Shading and Vertex smoothing and subdivisions modifiers. but nothing really gets that "single face" look. Any help would be appreciated.
Smooth Mesh Preview in Maya is the same as surface subdivision as far as I know. Subdivision modifier in Blender should give you very similar results. You can use Ctrl + 0/1/2/3/4/5 shortcuts to create a new Subdivision modifier and/or set the number of subdivisions of it.
