copying complex surfaces

I often have to copy large surfaces (exterior surface of body panels) which I do by 'surface offset' value 0. There can be 2000 faces to copy and currently I copy these by selecting them individually. No doubt this seems a silly question, but is there an easier way to do this (eg. I am told that Catia has a 'select tangent faces' function - I can't find anything similar (SolidWorks 2015)
