Searched online and in KiCAD menu options but couldn’t find a definitive answer. Is there a way to hide all the air wires making all the GND net connections in PCBnew?
I’m laying out a board and will be flooding it with a GND layer so the wires connecting GND to different point are not relevant and it would be nice to turn them all off so that I can focus on the connections that matter. I don’t have anything high power on the board so that shouldn’t be a problem. Thanks!
This is an often asked question and often requested feature. No, it’s not possible. Maybe in the future but not until 6.0, a couple of years away.
Many just use a ground plane to get rid of them. You obviously don’t have to keep it later.
It was one of my “must have” features before I will use KiCad. I found that I can easily manually delete GND net in netlist file. Working in Windows 7 I found that I can’t do that using Windows Notepad editor as it adds two invisible bytes at begining of txt file makeing it not readable by PcbNew (no effect of reading without any warning - I tested it with 4.0.7). But with Notepad++ works correct.
I planned to write a simple program to do it but I didn’t checked yet how usefull can be using ground plane for this. If it works well I will use it waiting for V6. I believe in V6 you will be able to change colour of net wires. I’m used to make my VCC red and GND blue (and invisible).
I really like the idea of changing colors to hide the nets. Wish I had spent more time coding so I could write something myself 
V5 is a huge improvement over V4 and I bet V6 will be the same. There are definitely things that could be better but I am extremely appreciative for all the hard work people (not me) have put into making this work, answering questions, and updating it.
As many other often requested features, this one is several years old. Add your vote. But there’s already a milestone attached so there’s a good chance of getting what we want (though it’s not certain).
Thanks for point that out I added my vote. I posted last week asking if another feature was available. I was looking to do cross select between the schematic and the PCB where you could select a number of components in a box in the schematic and it would select them for you in the PCB layout. That would make placement so much faster and simpler. Need to find out if there’s a request for that feature too. Wish I had enough experience coding to help out with this, maybe in time…
Currently, I print out the schematic/display schematic in other screen, and use T key, enter part reference on schematic in pcbnew to bring part into my focus and work with it. It pretty fast and simple.
For optimal placement, I turn off all the global ratsnest, and only click on the part pin of interesting net to show ratsnest that importance on that sub-set. But 5.x feature of ratsnest highlight had change to component base, so all the net of the component will show which all most have no use in this flow of work :-).
This request is rather complicated, and make it hold off for a long time. I had try request just much more simple (for coding) to just have it similar to 4.0.7 but have it more persistence (not reset when part get moved). Then it would be already pretty effective.
However, they close my request and point to this giant one!. My was: https://bugs.launchpad.net/kicad/+bug/1805460
you can also simply click onto the part in the schematic and kicad will do all of this for you. (At least in v5+. I am quite certain this also worked in v4.)
@Rene_Poschl - I’m not a fan of using mouse. Clicking on part on schematic, then move to pcbnew to work on it is very very slow due to the amount of hand movement. I print it for that reason, so I can just look and type. Some time it would be great to not having eeschema change it’s display/focus (it was distracted, and hurting the eyes compare to a printed out schematic on the table).
