I'm trying to convert an ArcGIS layer into a .kml format so I can use it in Google Earth. I've found several tutorials for this, but none of them have been helpful so far. They seem to be for an older version of ArcGIS, where the "Toolbox" drop-down menus provide a list of tools, one of which will perform the conversion. In my version (10.3), the "Toolbox" menu only gives me options for adding a new toolbox, opening a new toolbox, and opening a new Python toolbox. The ArcGIS support docs only give me lines of Python code which I presumably can use somehow, but I don't know Python.
How can convert this layer to .kml?
