Hello there,
I have a set of Protel pcb files or .ddb files which I successfully imported to CS. They happen to have system classes twice like in this post. I cannot edit or delete them because Error: "All Nets is a system class and cannot be edited".
So far they didn't cause any troubles, but now I want to import the files into KiCad where I get an Error because of double net classes. (Although the internet is pretty full of suggestions, the direct import of Protel files does not work in KiCad. So I have to go with the CS files.) I can import usual CS files into KiCad because they have only one "All Nets" class.
Does anybody know a way to get rid of the double classes? I even tried deleting the corresponding entries in the file via notepad++ but the file got corrupted.
Regards
