    Define CAM Document


      Hi ,

      May i know is it the same if i were to put "Custom" in the Document Type instead of "Routing / Split Plane"?


      For internal plane, i have set 2nd layer assign to Gnd  and 3rd layer as Pwr , but i do not want to put as CAM Plane, can i put as "No Plane" under layer setup?


      When i run the CAM, it prompt Warning-No Symbol for size xxx.xx - use symbol: +P, what does this mean? Is it critical? How to solve?



      Thank you .

          I use copper pours for my GND and Power plane layers, so I have 'Routing/Split Plane' selected.  The help button describes the different document types: 


          • Custom— Create your own definition for a document. Use the Select Items Dialog Box to specify which objects appear in the document.


          • Routing/Split Plane—  Document layers that contain plane areas and/or routing. Use this type  for Split/Mixed and No Plane layers. Conductive elements appear black in  the CAM Preview window.


          So 'Routing/Split Plane' is easier to use; you have more control with 'Custom'.



          I always use an external Gerber viewer (I prefer ViewMate, others like GCPrevue) to make sure my Gerber files are what I want.  You can play around with the different options for the layers and see what looks best.


          About the warning, check your drill table in your drill drawing Gerber file.  You'll see '+P' symbols.  These are acceptable but if you prefer something else, go to <File><CAM>(select your drill drawing)<Edit><Options><Drill Symbols...> and then hit <Augment> to add symbols or <Regenerate> to rework all the symbols.
