    Re: pcb-cutout Reply

     Hi,

    Your question is incomplete . what type  of cut out u want ? where u want ?

        > You can create NPTH slots , holes ...of required dimension in padstack  & create footprint for the same , then you can manually place that part in board where u want the cut out, it will reflect in your .drl or .rou file during drill file generation.

       > If it is a irregular shape cut out manually draw it using suitable class & provide the information about this cut out  in drill drawing artwork.Put all type keepout in the cut out region to avoid copper falling in this region [rout keepout /all. package keepout/all, viakeepout/all]

      >If the cut outs are at the board edge controll it by board outline .

     Not sure whether above line may help you requirement

    Regards,

    Girish

    Its difficult to explain the steps  for irregular shape outline .

    • Add line ,Arc W/Radius,3pt arc rectangle  e.t.c under Board Geometry /outline class  . look in to the different controls available  under option tab
    • Easy method :Irregular shape sounds like  you are making PCB for enclosure ,if yes get the DXF [2D] files from MCAD team &  import it under BG/Outline class .

    Best Regards

    RE: pcb-cutout Reply
    You can use two options to get the irregular shape outline

    • Manufacture->Drafting->create detail – use option tab to feed in the values and layer. you need to delete the multiple lines created inside the shape
    • Shape->Decompose shape to break the shape into lines.  And again you can do shape->compose shape and select the complete shape, in the option tab you can select the class/subclass, and the Line intersection requirement.

    Good luck!!

    Re: RE: pcb-cutout Reply

    Hello everyone.

     

    I need to cutout a PCB in a different way: Actually I need to cutout a small piece of the PCB in the BRD file, including parts of all the layers (planes, traces and pads). But I´m not interested in fabricating it, I just need to save this kind of "PCB biopsy" in another BRD file.
    Any idea how to do this?

     

    Thank you in advance,

    Juliano

    Re: RE: pcb-cutout Reply

     You can do this.  There are skill files available to "cut" through multiple layers so the copper can be separated from other copper first.  Then you can use "File->Export->Subdrawing" and follow the prompts.  You can then import the subdrawing into another board with identical stackup.  You do not have to "cut" first if you want all of the attached copper to export/import into the new board...just a useful step to know about.

    Also, there are 3rd party tools such as http://www.dalTools.com that can help with this.
