Prohibition Area

4RESTER

It's possible to make into the EAGLE the Prohibition Areas for the footprint of the component?

(see attached file)

    Yes, there are a few different layers that can be used for that.

     

    Right from manual (in "doc" folder on install directory) in section called

    Define Forbidden Areas

     

     

    Areas in the form of rectangles, polygons or circles in layers 41,

    tRestrict, and 42, bRestrict, are forbidden for the Autorouter/Followme

    router. No copper objects may be drawn in the top or bottom layers inside

    these areas. These regions are tested by the Design Rule Check and taken

    into consideration by the Autorouter/Followme router.

     

    Layer 43, vRestrict, is for drawing restricted areas where the Autorouter

    or the Followme router may not set vias. Manually placed vias in such a

    vRestrict region are not examined by the DRC and therefore not reported as

    an error.

     

     

    Note that vias in vRestrict area will not create DRC error (which is a

    problem CadSoft, that should be fixed IMHO).  Why have a restrict area if

    you don't report violations?

     

    But these just restricts copper traces and vias.  You can get component

    restricts as well.  Again, straight from manual section labelled Restricted

    area for components

     

     

    In layer 39, tKeepout, you should create a restricted area over the whole

    component (RECT command). This allows the DRC to check whether components

    on your board are too close or even overlapping.

     

     

    Note that tKeepout becomes bKeepout automatically when a component is

    mirrored in the layout.

     

    No allowance for internal layer restrict areas as of yet.  It's been

    requested many times and perhaps EAGLE 6 will make that available.

     

    Cheers,

     

    James.

    And here I thought the prohibition had ended in 1933 image
