There are lots of posts and movies around how to make a zone. But, In 4.0.4 I can’t see a way to delete a zone or reprocess it. Any ideas ? Thanks.
Hi Mario,
Select the zone tool and then right mouse button on the zone outline.
The zone menu offers delete and refill among many other options.
Regards,
Pedro.

Click it and press delete? ‘b’ to refill, ‘ctrl-b’ to unfill.

Pedro,
I can’t find the zone tool. There are buttons to add a zone and to add a cutout, but no explicit “zone tool”:
Thanks !
It is a bit tricky. you need to click on the boundary (that you drew) of your fill zone.
left click to get handles where you can drag your corners.
right click for everything else.
play around a bit and you will see what i mean.
In your case i think the boundary is at the same place as your edge cuts lines.
If you click there you should be asked if you want the boundary of the zone or the line.
The button tip says “Add flled zone”, the 6th on the right tool.
I just tried that. I can only add zones this way. I can’t edit them. (Yes the properties dialog opens, but it is for a new zone not for the old one.)
It looks like you are in the new OpenGl canvas. Then you must NOT have any tool selected to be able to edit, just about anything. Hit Esc, find your outline, either right click to bring up the context menu or hit e to edit directly.
Hi,
Rene, as yourself said, it is a bit tricky. Use the legacy canvas. Right click on the zone outline.
Then, move corner, delete corner, move zone or edit zone properties.
It is the same in opengl. (I just played around in legacy for the first time to test this. Concerning zones the two canvases are equal.)
It is only tricky because in most cases there is a lot of stuff at the same place as the zone outline.
(board edges, margin, footprints or other zones.)
It gets especially tricky if you have multiple zones within each other (each has its own priority.)
Then it gets sometimes hard to know which outline is for what zone.
By the way i could not work without the interactive router anymore. (This is the reason i switched from eagle to kicad. I never got used to the legacy stuff so i don’t really miss any features.)
Hi Rene,
Many features from legacy still need to be ported to openGL cavas. The push and shove feature is the great openGL one.
For zones, I can’t find move corner in openGL, and it is a must for resizing zones. OpenGL canvas is not mature yet, but it will.
I tried eagle around 2005 and found kicad better even though in that time kicad didn’t have the undo option. But this is a matter of personal preference.
Left click on the zone outline 
After that you can delete/insert corners by right clicking on the corner/lines
Move corners/lines by clicking and dragging on the Squares/Circles.
I don’t use push/show. I always use walk around and interactive drag. (The later one is fun. Activate it and just move [M] a trace and be amazed.)

Hi again,
Thanks, I see now how to move a corner. No need of menu entries.
Of course there are many other interesting features in openGL, like differential pairs routing. What I just pointed out is that not every legacy feature has been ported yet to openGL.
Interactive drag is amazing. Even for me, too used to dragging segment, keep slope 
Thanks ! The polygon outline and the board outline are at the same place. Case closed.
