I’ve been working on a schematic and layout for a couple weeks. I was nearing completion when the designers wanted to have 2 separate gnd planes. In the sch, I changed several GND symbols to GNDD; also deleted some components, no major rewiring.
I made a new Netlist and I believe it also reannotated.
When I bring up PCBNew, the existing layout is there, but when I read the new netlist, ALL of the components are floating and I would have to nearly start the layout from scratch. Looking at the small window in Reading Netlist, I see that all of the components were Del and then Added back in. How do I stop it from doing that?
Under what conditions does PCB decide to do this?
