How to ask for help and get an answer? Are no one able to help me? I also have problem with "Rebuild copper" function. It is not acting according to the design rules made in the project. Please help me.

@kosancrisplant.eje, Sorry but I can't help on this one, I'm not familiar enough with EasyEDA Pro.

Thank you for an answer andyfierman. Hopefully @support will start to be helpful. I can add some more info. Today I discovered that some of the net classes I made with only one net had come back although I deleted them. Then I tried to delete them again, but when I went into the "Design Rule" they had not disappeared - they came back. So support now is the time where you get into this case, please.

Just now I discovered the Delete menu, could this be the way to get rid of Net Classes, I hope so
