I would like to achieve the following: enter image description here

All the polygons are located on a single layer. I already tried to use SAGA self intersection with the "power" as an identifier, but I get wrong duplicates and overlapping polygons boundaries.

  • My problem with this method is that I get some faulty polygons (as shown on my post, the last image) and not the sum of all the overlapping polygons, only for the intersection of 2 polygons. – maevad01 Apr 11 '22 at 13:50

  • I don't understand your second image. Also, what do you mean by "faulty polygon"? – Stu Smith Apr 11 '22 at 14:56
  • Looks like you hit at least three polygons with the i-tool, I dont think there's anything wrong. Try completing the workflow in the answer I linked to – BERA Apr 11 '22 at 16:12
