Hello, I am working in ArcGIS Desktop 10.7.1. At some point when working on my project a grid appeared (pics attached) and I do not know how to get rid of it. The grid is diamond shaped and black and the grid adjust in size as I zoom in and out. IDK how it cam on as all I was doing was altering some shape files and using the 3D analyst tool to create some elevation profiles when it appeared. The "grid" does not appear to be attached to any of my current layers because when I turn all of my layers off the "grid" is still there. I need to know how to turn this off/get rid of it because it still appears when I go to layout view and ruins my map.
