KiCad 9 - Duplicating Edge Cuts to another layer

I’m new to KiCad so until now all my boards have been simple rectangles. Now I’m trying to make an enclosure using PCB so there are notches and holes on Edge Cuts that will be routed by the PCB shop. I want to fill both sides of the board with copper zones, and to avoid having to re-create the complex outline I’ve been trying to duplicate Edge Cuts onto F.Cu and B.Cu so I can then fill these zones - but without success.

I can duplicate the outline OK but am unable to select the new version and change the layer because the “Properties” option is not available when I right click. I’ve tried Grouping but that doesn’t work either. I can select each individual line segment and Properties appears, but is there a way to change every line on Edge Cuts at one time? Thanks.

No. Don’t even attempt to do this. Just draw only on Edge.Cuts.

For the copper layer, just draw a big shape around the PCB. KiCad will clip the copper at a set distance from the edge of the PCB.

I prefer to use a weird shape such as a pentagon for the actual zone. This way, when the whole zone gets flooded because of for example an error in Edge.Cuts, then it will be obvious immediately when Gerbers are generated.

Having KiCad clip your zones is far superior than managing this yourself. Especially when the PCB outline is being changed in a revision, the copper layers will adjust automatically, after a zone refill with b.

Got it, thanks! I may have been reverting to Eagle-think or something but was stuck.
