Automatically Update Gerber Prefix to Current Filename?

JFuoco

When generating Gerbers, is there a way to set the "Prefix" cell (or Suffix, for that matter) to the board's filename? This way it will automatically update as revision numbers change, and doesn't have to be manually updated?

For instance set it as $FILENAME_ so if the filename is jim_pcb_v00.brd the gerbers become jim_pcb_v00_top, jim_pcb_v00_bot, etc. but if updated to v01, they will become jim_pcb_v01_top, jim_pcb_v01_bot etc, without having to manually update the Suffix cell highlighted below?

    ARTWORK_PREFIX

    The ARTWORK_PREFIX property, attached to a board (design), adds a user-defined, case-sensitive string before generated film filenames, allowing a maximum 250-character filename, such as a part or revision number, which may be useful for larger boards with many layers and numerous artwork films as a result. For example, if a board has a project number of CDS1234, adding a prefix of CDS1234_ creates artwork in the following format:

    CDS1234_TOP.art

    CDS1234_BOTTOM.art

    CDS1234_SMASKT.art

    CDS1234_SMASKB.art

    Thanks David -- but I'm not sure thats exactly what I want. I want to be able to put a variable as the ARTWORK_PREFIX property that populates the filename. So that if I rename my project from CDS1234.brd to CDS1235.brd. the ARTWORK_PREFIX is automatically updated to CDS1235_ without my manually doing it.

    We'd also be quite interested in how to do this.. Is this some setting that is project specific?

    The only way I could think of would be to set the variable when the design is opened, however that doesn't cover your 'save_as' scenario, below is the code I added to my allegro.ilinit file:

    procedure(MyTriggerOpenSetArtPrefix(t_open)
    let( (Value Status)
    (Value = (strcat (axlCurrentDesign) "_"))
    ;(axlMsgPut ";#artwork_prefix %s" Value)
    (Status = (axlDBAddProp axlDBGetDesign() list("ARTWORK_PREFIX" Value)))
    t
    )
    )
    axlTriggerSet('open 'MyTriggerOpenSetArtPrefix)

    Oh wow that's a great idea, I'm going to give that a shot.
