I don’t know why you have been working on this for a few days… It only takes a few minutes to make one… Just kidding…
See attached, This is a Donut I made for andy, http://imgh.us/Andys_Donut.svg , to see how it is written.
You need the layer: “board” with the object “boardoutline”. this needs to be a single object.
Layer: “silkscreen” is the top of the board and the Layer: “silkscreen0” is the bottom, Silkscreens can have as many objects as you would like.
<g id="board"> <path id="boardoutline"/> </g> <g id="silkscreen"> </g> <g id="silkscreen0"> </g>
To import the PCB, highlight the pcb in the view and click “load image file” in the inspector.
