Rename existing floating wire segment in board

autodeskguest

If a signal segment has the signal name of an existing net present in

the schematic, Eagle refuses to rename it. You will get "please do this

in the schematic" message.

 

Now, if this segment was "floating", meaning it was not connected to any

of its target pins, or ending in airwires, why prevent this renaming? I

do support this "error" message when it is connected to one or more

target pins (although sometimes I would like to override it).

 

For now, I will write this function into my toolbox (ulp).

    if I understand you correctly, you want to 'reuse' an already routed

    track for a different net.

    After the rename the original net then would have an air wire instead

    of the track.

    Correct. I am doing large designs and sometimes I find a long wire

    segment already laid down is more suitable for a different signal, or I

    simply want to swap two wire segments because it will ease routing.
