Open an Orthographic 3D View (not perspective). Right click on the View Cube in the 3D View, pick "align to View" and find a Section or Elevation. The view will automatically create a section box on the cutting plane of the Section or Elevation View and align the 3D View to that View. You use an orthographic View as this gives the illusion of it not having perspective and looks like a Section or Elevation. Note you can also align the 3D View to Plan Views so that you can create 3D renders that look like normal Revit Plan Views.
Works an absolute dream! Exactly what I was after, Cheers.
