If you remove an object that has a clearence in a polygon, the polygon=20
should be updated and the clearance should be gone. If it doesn't happen=20
immediately it is a bug. Once you save and load the board, it will surely=
=20
happen because the polygon is recalculated on load.
For what you said there was another hack: to use lines with width=3D0=20
(and keep those lines). That would still apply the clearance, but since=20
line with is 0 copper would not appear on some output. I am not sure which=
=20
output formats did or did not break on this.
