I had a question here earlier about how to properly format output from excel to make use of the import profile from file command. Basically, I formatted the output as space delimited file and had to adjust the column format as well. I put instructions on my websitebecause we use this function quite a lot in stream restoration design and someone might find this handy: http://civil3d.streamrestoration.info/2009/02/import-profile-data-from-excel.html
