I’ve been trying to export a .DSN file from pcbNew, and keep getting the error message above. No parts are ID’d under “G.”
In Cvpcb, there are no parts that are ID’d as “G***”. Perhaps this has something to do with GND connections? That would be my only guess.
I’m stumped. I’m wondering if this is a software issue with KiCAD, or if I’ve missed something.
Ha! I’ve found the solution. The problem is that I had multiple “logos” on my silk screen layer. These logos are technically components, but they do not show up in Cvpcb. The solution was to find their ID (labeled as G***) physically on my PCB and manually edit their ID’s to G1, G2, G3… etc.
In addition to logos (company logos, the ROHS logo, open-source hardware logo, ESD logo, etc), mounting holes get the “G” designator if they are added as a footprint.
This situation has never caused a problem, or generated a DRC squawk, for me . . . but I have never tried to use the autorouter.
