I am trying to remove the values that eagle draws on the board by default. There is a component that I wish to delete the value but it came up with error saying "Can't backannotate this operation. Please do this in the schematic". What I do is typing in sma to smash the components and then typed in dele to delete the values so I understand how to delete value names. Why did this error happen?

If you could upload the sch and pcb files and specifiy what changes you need, a clear reply could be obtained faster.

If you have the schematic developed for the same, you need to change the concerned values there. later they would be copied into layout automatically.
