I have a multi-layer design with multiple ground plane layers. But these have issues with ground loops. How can I set something in PCB Editor 16.5 that will only connect vias to one ground plane layer and leave all other layers unconnected, so that I can use a single ground connection point.
That almost worked. I set the thermal relief for global dynamic shapes to none. Selected the shape where I wanted the connections and RMB the selected parameters and changed the thermal relief for that layer without problems.
But the single pin to connect the other planes did not work. I have added 4 traces from that pin to the copper pour for each layer instead. This has worked this way.
