hi, guys
I encountered an issue when I was editing a sketch, the system give me a hint: you could not add or delete the reference,
thanks in advance
Probably the feature described by the sketch is mirrored. You will need
to delete the mirror, make the change and remirror. Usually the mirror
command is not as useful as it seems.
