          •  Automate conduit bending by:
            –  Providing import files directly to the
             bend machinery
            or
            –  Providing build sheets and mark
             instructions for each bend

          (This last point enables the shop or
          field electrician to operate the benders
          without pausing to calculate bends.)

          Again, when you demand that your
          fabrication software has this trade
          know-how at the front end, you reap
          the benefits of an extremely lean and
          productive fabshop on the backend.
