I open the MultipleRingBuffer and chose the Input Feature, which are lines, and give the output next to my polygons. I put a distance of 300 and choose meeter. I give it a simple Field Name and click okay.
Down at the Bottom i get the info that the tool worked out but the buffer it self dont show up on the map also not in the table of contents and it is not saved in my folders.
All my objects have the same projection.
What could be the Problem
