How to do a cut in the middle of the polygon on Altium Designer 19?

Hi everyone,

I'm wondering how to do a cut in the middle of the polygon using the Altium. It seems it has the tools just for making the cutouts and splitting the planes, but not making the cuttlines in the middle of the plane. Tried various methods to achieve this, but unsuccessfully. It would be great if someone could explain how this could be done. Thanks!

You mean to make not just a concave cut from an edge, but an actual disconnected hole within the polygon?

Try a Polygon Cutout Region, or try pulling in the perimeter so it necks down then opens up to make the hole.  The latter is not preferred because the minimum neck width trimming algorithm tends to clip corners even if they aren't acute corners, so the seam tends to have bites missing from it.
