as a Student of Geography i use ArcMap for Desktop (10.6) on Windows 10. Everytime i try to do this, the system fails: Activate the button 'Select Features by Rectangle' in the Tools Toolbar. Select every polygon
which is not visible in the ancient map by pressing the Shift-Key.
Thanks for helping!
it is probably a projection issue. Are you using a regional projection? Some your polygons may be out side of your projection area. Copy the date to a new database with new feature dataset that is using a world wide projection
