    How to import and verify the Gerber files in Allegro. Reply

     Dear All,

    I have generated the .drl and .art files for my PCB for manufacture in Allegro 16.2.

    But, I want to import them and verify that it actually properly generated.

    Please tell me how I can import and verify that it is correctly generated.

     

    Kind Regards,

     There are a lot of Gerber file viewers available, both free and otherwise.  You can also import the artwork (gerbers) into an Allegro board file using File => Import => Artwork.  You can specify unused layers in your current design, or create a new board file in your directory specifically for viewing the artwork.

     But it seems I can not import "outline.art" "pastemask_top.art" "pastemask_bottom.art" back to the board file.

    For outline,

    it says "W- Layer BOARD GEOMETRY/OUTLINE does not support raster formats
    E- *Error* car: Can't take car of atom  - "PLATING_BAR" 

    There is no class for pastemask_top and pastemask_bottom.

    Thanks a lot.

    That's all correct. The Gerber data is "dumb", actually contains instructions to control a photoplotter and no design intelligence. The PCB Editor database layers have some minimum expectations about objects added to them to assist the design process.

    Create a user defined subclass, Setup>Subclasses, pick the button next to Manufacturing, type the name(s) of the user defined subclass(es) to add, close this form and the Subclasses form. Check the "world" is large enough to accept the drawing data through Setup>Design Parameters, then File>Import>Artwork, specify Manufacturing / <new subclass> as the destination for the imported artwork data. After importing the first film, you can opt to reuse the previous origin if you want to superimpose the artwork data from each film.
