Please see: https://easyeda.com/Doc/Tutorial/PCBOrderFAQ.htm#V-cut-V-Groove `1. The V-cut line should be the same as the outline of the Sub-PCB. That is to say, there is zero space between the sub-boards.` ![enter image description here][1] [1]: /editor/20180131/5a70bdfcba153.png

Ok ,I try your solution but I have this message : "EasyEda does not allow innerboard outline cut-out, please use solid region or hole"

Each PCB is inside its own rectangular board outline. They are side by side so one is not inside the other. PCB1 is inside one, PCB2 is inside the other.

@andyfierman I tried this on my own PCB design where I want two similar designs to be on the same panel, with a V-cut between them. However, every time I try to 'rebuild the copper area' for my ground plane I get the error "EasyEDA does not allow inner board outlines to form cut-outs, please use SolidRegion or Hole". I am not trying to create a cutout, i want the boardoutline layer to look as the example does above, with two touching rectangles, side-by-side.

Hi Simon, I think you have found a bug as reported here: [https://easyeda.com/forum/topic/Multiple-board-outline-with-copper-area-bug-7dab95f432ff4efab5a64eb1a04568c3](https://easyeda.com/forum/topic/Multiple-board-outline-with-copper-area-bug-7dab95f432ff4efab5a64eb1a04568c3) There are also a couple of other problems. 2\. These diamond shaped regions:  are not allowed. You may only create continuous straight V-cut lines that cross at right angles to each other as in my illustration above and the demonstration PCB in my bug report:  3\. You must also take care that the end points of the lines used to construct the board outlines snap exactly to each other to ensure that the board outlines are closed\.

You can probably replace your diamonds defined by board outline regions with either round Holes or diamond shaped Solid Regions set to "NPTH".

Hi, Thank you very much for your help and support. Your explanation was clear and easy to follow. I have now made the changes you suggested. The complete board outline is one solid track running all the way round the outside and joining exactly back with the start point. The v-groove lines are all unbroken straight lines that cross at right angles to one another. The diamond shaped cut outs are solid regions of type 'NPTH'. I still get the 'pcb outline cannot be used to create cut outs...' error that you documented in your bug report, but hopefully this design can now still be created by the manufacturer. Am I correct in thinking that the 'Document' layer can be used for notes such as the 'v-groove' markings and is not used by JLCPCB? Again thanks for the assistance, really helpful response, and please feel free to check out the final design and comment if you think it is acceptable for manufacturing now.

i i have also tried the same but when generating gerber it is showing one pcb only any clue

Please read the Tutorial about V-Cut and panelization. EasyEDA draws one PCB. JLCPCB then creates the copies.
