Thanks for the reply,
From what I read from the help, the tool creates a table and optional graph denoting the profile of line features over one or more multipatch, raster, TIN, or terrain models. Thus uses multiple rasters with only one profile or transect.
I need the opposite, several transects over one DEM. plus I´ve looked for the tool and apparently it is only on arcgis 10.2 and I have
arcgis 10.0
Thanks again.
