I have added dimensions to a PCB, and now they won't delete, I have tried to select at the ends, and at the midpoint, or select them as part of a group. I have added new dimensions to the PCB, and I can delete these, but the existing dimensions can't be selected. I have turned off all layers except layer 20, (the layer on which they on) , but when I try to group them Eagle says the group is empty.
Any ideas how to remove them. When I used PADs for instance I would export as an ASCII and then re-import it. Are there any such work arounds for Eagle.
