I am required to open a bunch (50 per week) of mxd's and 'Clear' the Coordinate system from the data-frame to make sure my students have all of their data projected in the same (correct) Coordinate System, to see if their data 'lines up'.
I do this by hand, over and over and over, by using the steps below:
-Right Clicking the Data Frame
-Go to the Coordinate System Tab of 'Data Frame Properties'
-Click on the Globe dropdown arrow
-Scroll to 'Clear'
-Click 'OK' or 'Apply' as I watch to see if any of the data disappears.
There has GOT to be a way I can copy/paste a short line of Python into the Python Window to automate this. I know I could write a complete script that would check the coordinate system of each layer in the map without actually opening the map, but I'm just looking for a quick fix that I can do while I also evaluate their cartography.
I am using ArcGIS 10.2.1 for Desktop with an Advanced level license.
