altiumpolygonsplit
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!
Btw this is just an example what I'm trying to achieve
Click on Place Polygon Plane ( 
). On the dialog, in the Net Options select the specific net to which your component is connected.
Then draw the desired shape for your polygon(s).
In the Polygon Pour properties window (your last picture) for each of the polygons, under "Net Options" change the dropdown from "Pour over same net polygons only" to "Pour over all same net objects". Then repour the polygon (T-G-A). This should connect the tracks to the polygon.

Basically draw a line, select it and go to Tools -> Convert -> Create Cutout from Selected Primitives and repour the polygon.
