And the last my question for today.
I'd like to put many vias connecting top GND with bottom GND. How to do it easily?
When I copy the GND via (by Ctrl+D) and put it on GND filled place it not gets being GND and also to put the next one I have to start the process from the beginning. Is there any way to put via after via all over the PCB and make them all being GND?
When I try to route track from GND via to such 'yet not GND' via router doesn't allow me for it even when I switched of DRC.
This works that way under F11. Under F9 I can route to that via, but they sometimes get being GND and sometimes not. I don't detected what decides of it. If they not, then refilling the GND zone makes wholes around them. I must have reliable method and not that sometimes works and sometimes not.
I can route switching top/bottom/top... but at top I have something else (at bottom I have only GND) so I would have to place many times 2 vias to be back on bottom to be able travel forward and than I'll have to remove this extra vias. The best would be if those vias just be GND and I have no need to connect them with paths but only with GND copper zone I have at bottom. When I try to edit the via parameters I can't set their net.
Till now I can't find the enough easy way to do it but I suppose the reason can be that I have not done any PCB with kiCad yet.
I'm just testing if everything, I need, will work before starting the first PCB.
