Hello everyone,
I have a kelvin connection on a sense resistor. On both sides of the resistor, I have copper pours to electrically connect the pads to their corresponding parts.
I have a couple of vias going back to my buck controller chip. What I want to do is to not have these vias being electrically connected to the copper pour even though they are connected to the same net. I was able to achieve this in my old software.
Here is a screenshot of what I want to do:
How do I do this in KiCAD?
Add a rule area from here: 
Ok, that isn’t too bad. Any chance I can make it a circle instead of a square?
I have never done it but probably net-tie is what should be used here. That way even tracks are copper connected they are different nets so zone fill will not connect to the other net.
Isn’t net-tie used to connect two or more pads (or holes) of the footprint together? Like if you have a controller module with multiple gnd?
A net tie is to tie two Nets together, and that is indeed the best approach here. If you put the net ties near the sense resistor, then the feedback lines will have their own net name, and therefore KiCad will calculate further clearances for you. This also removes the chance of accidental deletion (The Interactive router likes to delete “double” connections) or accidental shorts on other points along the feedback lines.
Place a circle on the Margin layer (concentric with the via). That should keep the pour away from the via. As a consequence, it will also keep everything from connecting to the via.
