Back Annotation of references

autodeskguest

I've searched but cannot find how to force a 'back annotation' of all the

component reference designators.

 

Once I'm done with a layout I want to 'run something' that reorders the

refs; top to bottom, left to right.

 

How's it done?

 

Thanks.

    When you hand a board to an assembly house they are not pleased by a

    completely random spattering of the part numbers.

     

    Then you need a better assembly house or better documentation.  I renumber

    the component designators for reasonable order in the schematic, and things

    fall where they fall on the board.  However, I do provide a board drawing

    with all the component designators on each part and a locator index that

    gives both the schematic coordinate and the board coordinate of every

    part.

     

    So far no assembly house has complained about that.  In fact, one local

    assembler even mentioned to me she likes my boards because of the nice

    documentation I provide.  The ULPs and scripts for making the assembly

    drawings and the locator index are included in my Eagle Tools release

    available from http://www.embedinc.com/pic/dload.htm.  In particular,

    INDEX.ULP generates the locator index, and GRID_BRD.ULP in conjunction with

    GRID_TOP.SCR and GRID_BOT.SCR create the assembly drawing.  These also

    assume the component designator for each part is in the tDocu layer of all

    packages.
