I am trying to import survey points with linework using a fieldbook file, but when I import the file, it gives me an error stating that I have duplicate points.  I have read through the file (consisting of 74 points) and I can't find two points with the same point number (either in the fieldbook file or the original ASCII file).  I have even tried renumbering the points, but that didn't work.  Does anyone know why I am getting this error?
