The information in the EasyEDA Tutorial about which layer V-Cut lines are drawn on appears to be incorrect: [https://docs.easyeda.com/en/PCB/Panelize/index.html](https://docs.easyeda.com/en/PCB/Panelize/index.html)<br> <br> According to @JLCPCBsupport, **V-Cut lines must be drawn on the Board Outline Layer** in the PCB Editor. Please see this topic: [https://easyeda.com/forum/topic/V-Cut-irregular-size-panels-how-to-specify-65fd87a596ec4fdba6bae81e5e16e90b](https://easyeda.com/forum/topic/V-Cut-irregular-size-panels-how-to-specify-65fd87a596ec4fdba6bae81e5e16e90b)<br> <br> Ensuring that V-Cut lines must appear on the Board Outline Layer is also described in the JLCPCB  FAQ advice item (7) here: **7\. Designs about slots/CUT OUT/ millings/ v\-cut** [https://support.jlcpcb.com/article/68-instructions-for-ordering](https://support.jlcpcb.com/article/68-instructions-for-ordering)<br> <br> Text, comments and indicative lines can be on the Mechanical Layer but the V-Cut lines must be drawn on the Board Outline Layer. Please correct and clarify the EasyEDA Tutorial to clearly state that **V-Cut lines must be drawn on the Board Outline Layer** in the PCB Editor. Thanks.
