You have to add the vias to the samevl net as the copper areas.

It appears the VIAs are not in the same net as the copper area, so are having isolation rings added.

Check the net and try changing it to the same as the main area?

It's not a program I've ever used, but that is a typical different-net effect.

Yes, you are right, that's one problem. But after changing it to the same net as the copper area. It became this crossover shape in the picture below. why did it happen like this?

I haven't used Altium, but I suspect you've added a PAD, intended for soldering a component to –:the cross provides thermal isolation from the plane to make soldering easier – instead of a VIA, which won't have thermal isolation.

I don't think so. When I double click the component, there will be a column in the properties box showing the Via type and feature. And if that's a Pad, it will show the Pad features. It's different text, I'm pretty sure about that.

In the via properties box, there should be a check box for Thermal Relief under the Via Stack section.

Uncheck that box for a solid connection.

I don't have Altium Designer, but found this info here: https://www.altium.com/documentation/altium-designer/pads-vias

Thanks for posting this link here. But all of the Thermal Relief boxes remain unchecked. I don't think anything wrong with it.

Take a look here for stitching.

Yes, it works. I got the answer from 'add stitching to net'. Thank you very much!

I'm sorry there seems to be another problem. It really reached the effect in picture 1 in 3D model, but in 2D model if double click the via, it still shows a crossover pattern like in picture 5 and it should actually be the pattern in picture 4. Besides there are no signs of using stitching in picture 4 and it really looks like a normal via. So that maybe not the best way to reach the desired effect. I'm still working on the solutions and any help would also be appreciated.

You might try asking in Altiums forum.

Hello, I found the answer at Design>Rules>Plane>Polygon Connect Style>PolygonConnect. I set the Connect Style to Direct Connect and I got the results I want. And there maybe some distortion to the via connection to Polygon in some layers after resetting, just redraw the polygon and the problem is gone. Yes, you got that idea. It is indeed something related to Thermal Relief box, but we can reset this box using this method. Hope this maybe useful for someone who has the same question.
