Hi, everyone!

I am struggling to find ways to "clear" the projection in ArcGIS Pro. I thought it existed a few versions ago but now I can't find it.

There are plenty of places for this - on feature classes and on the map itself.

Guess I miss that "undefined" projection in general!

Thanks,
Ryan

Ryan,

This article may get you part way there. https://community.esri.com/t5/arcgis-pro-questions/how-to-clear-the-coordinate-system-of-the-map-to/td-p/120403/page/6

I just did some testing and besides what the article recommends. I created a map with the unknown coordinate system. Pro no longer lets you favorite the unknown coordinate system. Instead, I used define projection and set it to unknown from the map. However, I don't know if this will do exactly what you are wanting as it doesn't seem to really clear it. It just defines it as unknown. When I tried to bring the file back in with the unknown coordinate system it still put it in the right location, so you might test with whatever you need it for.
