@andyfierman Nope.  Shift B doesn't seem to do anything anymore, nor can I see it in the list of shortcuts.  In fact I can see no way of actually removing a ground plane once it is in place other than deleting the outline which is ridiculous.   It can be hidden but is still visible to the DRC so if I have line to line DRC set to wide, then check it, then copper fill to tighter dimensions as one does for r.f., it's a once-only operation which is useless.

Is this in the Desktop Client because when I do SHIFT+B in the online version, it rebuilds the copper area. SHIFT+M toggles visibility but only if at least one copper area outline is selected. Sorry if I'm missing your question. Could you explain more?

Yes it's the desktop client.  I used to be able to actually remove the copper area, not just make it invisible.   When invisible, it is still visible to the DRC so this fails as I route track to ground plane closer then track to track.
