    Replace Obsolete Symbols Reply

    I have a make-from design that includes obsolete symbols no longer included in my library. I would like to replace these symbols with a new footprint available from the library without losing any of the connections.

    How do you update obsolete symbols in a design? Any tricks?

     I'll assume when you mention these "new footprints" you mean they have a new JEDEC_TYPE name? If so, that's ok to:

    1) Export a placement file from the current board

    2) Import a new netlist (that might remove parts that have been renamed

    3) Import the placement file (old placement). This will replace only the parts awaiting placement

    4) Finally? Run Tools/Derive Connectivity - this should connect what might be been unconnected.

    Good day.
