I'm currently doing a very complex circuit board in eagle.
Currently I defined 7 classes of which 6 I am using. the seventh I want to delete since I no longer need it.
First I tried the command "class -n" to delete the class where n is the class number I want removed, and I got the error "Net class n is in use"
So I am in my board, executed the cmd-change-class.ulp script, then I put in the correct values for the options:
I specified for current class in board the one I want to remove I specified "default" for the "change class to" field I specified mm for grid since that's what I am working with
Then when I clicked OK, the box simply disappeared and I got no indication as to whether the operation was successful or not.
So then I tried again to remove the same net class again as before and I still get the same error: "Net class n is in use"
Rather than highlighting the entire circuit and changing the class to one class (and wrecking my class settings for other nets), what is a simple solution to this problem?
