I have a problem with my Arcmap (v.10.3.1), I am trying to use the contour tool using the deriving data from my DTM (8mt) but it doesn't work. I used this file for other tool and it always worked. Anyway, I presumed that it was the file the problem, so I started to use the Slope file as attempt but when I try to use the contour tool Arcmap crashes blocking itself or shutting down directly.
In your opinion, what could be the cause?
Thank you in advance
