I need to find a way to create a line at the location the data frame cuts off a map. Any ideas?
I have not used this tool, but it might do the trick. The result is a polygon feature class of the map extent. In your case, you can then convert it to a line with the Feature to Line tool in ArcToolbox (and then delete any unneeded linework).

I just downloaded the tool and ran it. This was exactly what I was looking for thank you!!!
