Altium Designer: Polygon does not connect to the pads on the same Net

I'm trying to put a plane shield using polygon pour and I realized that some object is not connected to my polygon. In the picture below it is clearly seen that the GND through hole is not connected to my polygon that is declared as "GND". I can't…

When and why is it important to route with polygons vs. traces?

I'm (still) a relative beginner in PCB layout. I'm trying to understand in what scenarios it's important to route with polygon areas instead of traces, and in those scenarios, just how important it really is - and why. X/Y disclaimer: the motivation…

Ground Plane on Top and Bottom layers in 4-layer PCBs

Is it a good idea to fill free space on Top and Bottom layers in a multilayer (4-layer or more) PCB? I usually use external layers for signal routing and internal layers for power supplies and ground. * Top - Signals, High speed signals (if there…

Using polygon pours for small signals in PCB design

I'm trying to improve my PCB routing skills. When I started out a few years back, I just layed out the components and ran tracks with a fixed width between them. I didn't even know about polygon pours. Then when I started working with switching…

Altium: Remove small sliver openings in hatched pour

One of Altium's polygon pour modes is a hatched version, which allows the user to specify an individual track width and a grid size and it automatically generates a pour in a cross-hatch pattern. It also generates solid borders around component pads…

How can I set a clearance in my polygons? Because there is an error of short circuit between poly of GND or 5V and my vias

I tried to solve these errors using blind and buried vias, but the errors persist. I want when I repour the poly, it creates a clearance between the vias and poly. Or another solutions for the error. It is a 6-layer PCB.

Altium - Polygon pour into a cutout

I'm using Altium Designer 22 to design a PCB. On the top layer I have a ground plane with a hole in the middle. I made the hole by using a polygon cutout. Now, I have to pour into this cutout region some polygons, but I'm not able to do this. Do you…

How do I change and select which Polygon thermal relief Altium Designer 19 shall use?

How can I make a polygon in a Signal layer in Altium Desginer 19, to change its copper thermal relief? I've created a rule for it, or so I think. But I have not been able to find where I select which rule the Polygon shall follow. In my case I want…
