I'm new to ArcGIS and in a college course. I am trying to perform a Line of Sight analysis on a DEM raster, but it's only showing the endpoints, not the intermediate line with the visibility information in red and green.
I'm running it from the 3D analyst toolbar.
I have double checked everything that the textbook, Discovering GIS and ArcGIS, has specified, and my prof has no clue what the error is.
What do you think is the problem here?
I know it's not much to go on, but I can't find a similar issue anywhere.
