Draw a big circle. Then a smaller one on top and then a smaller one and a smaller one.
You see a stack of circles like a bullseye. If you had drawn these in QGIS the other way you would only see the largest one as it hides the others.
Is there a way in a single layer to slice every feature with every other?
Basically, I have contours and I only want the band between each polygon rather than the stack of progressively bigger polys like the bullseye example.
I have perfect data where all polygons are closed and sit perfectly inside each other.
