How To Delete An Orphaned Trace

Former Member
Former Member over 15 years ago

I found when I make a small modification to a project with schematic and

PCB, I'll sometimes end up with an orphaned trace. That is, a short trace

which doesn't go anywhere anymore.

 

I don't see a setting in the DRC rules to catch this. Is there a way to

automatically find and tag these so i can delete them? Sometimes, they are

short enough that my tired eyes miss them. I'm loathe to rip up and redo

the board as these are typically minor changes to isolated parts.

 

Thanks

 

David

    The problem is the traces are "routed" in a sense.

    For

    example, it I delete a component, the traces to that component are

    not

    ripped up. So, these orphaned traces are still connected to the

    proper net.

    A Ratsnest command doesn't show them and they are still on the top

    or

    bottom layer. It can also happen if I don't fully ripup a trace and

    miss a

    small piece sticking out from a pad.

    When there 'are' unrouted sections to detect it can be done with the ULP

    ULP zoom-unrouted

    ftp://ftp.cadsoft.de/eagle/userfiles/ulp/zoom-unrouted.ulp

     

    It will zoom you to the first unrouted trace it finds on the board.

    After removing a part, a ratsnest will likely create an unrouted trace so

    you can detect the unattached  routed trace.

     

    Another ULP to detect a single ended wire

    find-single-ended-wire

    ftp://ftp.cadsoft.de/eagle/userfiles/ulp/find-single-ended-wire.ulp
