Change the layers of some designs

Group all of your notes. If you want any of the remaining sections to fill, set them to fill before doing the following. Duplicate your black circles. Select the grouped notes then shift select one of the black circles. Go to Tools> Cut shapes. Click off the image, select the center notes group and shift select the other black circle. Go to Tools> Cut Shapes. You now have 3 separate shapes. You can select the inner notes and change to black, if that didn’t happen when cutting and repeat for the outer notes.

The easiest / fastest solution is to group all the objects and create an outer offset of 0.1mm or so. Then you get another cut line on the outside. Though, this is not a perfect solution, since you have increased project duration because those areas are touched twice.
