HI Everybody. I am having problem setting up clerances for each polygons connecting to different voltages. How do I go about it ? Altium keeps ignoring the rules I set for each polygons. I use ''belongs to polygon'' command and choose the net its connected. I also set the priorities but no use....I have 24V,5V and GND.( I am not using a ground or power plane) Its a 2 layers prototype board.

What exactly doesn't work? Could you zoom in the part of PCB which is wrong, so we can see the polygons and net names (same as I did in my screenshot, you can clearly see, that between PHASE_1V375 and +1V375 polygons is bigger gap 0.2mm comparing to polygon vs track, that is 0.1mm gap).
BTW: you rules look unusual, you may be missing a general clearance rule All - All.

I used the cut outs and selected copper then It kind of worked. But I can't still manipulate the clerances independently. I also got an error on one of the cut out as there are two ground vias inside it connecting a large cap to the bottom ground but Altium doesn't create clearance around the vias. Please see the picture.Last edited by ican7; 12-22-2016, 10:13 PM.

Still not doing anything. I am just wondering how did you create that polygon in the picture for the 28 pins project. Its surrounded by ground polygon with a proper clearance and its also showing in the polygon manager as a polygon. Using cut outs? If so how ? the ones that I created didn't show in the polygon manager and not behaving as the usual polygon.

Yes, this small polygon is done through cutout. If you have downloaded the 28pins, you can click through it. There is nothing special:
1) Create big GND
2) Create cutout in the GND
3) Draw +5V/3V3 polygon inside the cutout
