    Anti etch shape not visible in gerber artwork Reply

    Hello all

    I am using PCB Editor 16.3.  I have some areas of copper voids on my ground and power layers (negative artwork).  The shapes are visible in the .brd file and is of the class "Anti etch/Ground" and "Anti etch/Power".  I have added these classes to my artwork control form but I don't see the shapes in the resultant gerber files.  Anyone have any ideas of what I am doing wrong?

     

    thanks

    When generating a negative artwork, the shapes on the artwork layer will become clear (negative image) so you will not see the shapes that you have defined on "Anti Etch/Ground" and "Anti Etch/Power".  Defining the copper voids as lines on Anti Etch will show up in a negative artwork output.

    Not sure what you are exactly trying to do but if you copy the "Anti Etch/Ground" and "Anti Etch/Power" shapes to "Route Keepout/Ground" and "Route Keepout/Power" they will add copper voids on the plane shapes, granted the plane shapes are dynamic. 

    You could also manually add copper voids to the plane using Shape > Manual Void but I would recommend using Route Keepout shapes and changing your plane shapes to Dynamic, if they are not already.  Using Dynamic shapes on a Negative artwork layer is perfectly fine with the added benefit of automatically voiding Route Keepouts.

    Hope this helps,
    Mike Catrambone
