  • Richard,

     

    I'm down to only one mystery (at least until I make CAM files, which is tomorrow's adventure :-)  

     

    On one of my boards DRC returns a Drill Size error on layer 20 for every via.  The vias are well away from the board edge and other drill holes and other components etc.  I don't get what it is seeing.  My other board does not do this yet the vias are the same size and the design rules are the same for both boards.  Do you know what it is complaining about with these errors?

     

    Thanks - couldn't do it without you!

    I see what it is doing now.  When the stop mask layers are on, it throws  a DRC error to anything that violates the stop mask - names, values,  place, origins.  Whatever is displayed in the image is tested against  the stop mask.  So see if there are any real stop mask violations, I'll  have to turn off all the layers that print or draw anything other than  top and bottom traces and vias and pads etc.

     

    Maybe you defined a drill size value for net classes?

     

    Regards,

    Richard

    Richard,

     

    That's a good thought, but the only net class that exists is the default and width, drill, and clearance are all 0.

     

    The via sizes, drill sizes, restring, and all design rules are the same on both boards.

     

    Why is layer 20 involved?

     

    Thanks,

    Hi Michael,

     

    I am glad to read that you got out what the problems were, and to be honset, I am glad that the problem was not an EAGLE fault. image

     

    All the best,

    Richard
