Yeah I know. I put a request for bigger X,Y coord box and a ruler as a patch, but that was a while ago.
In actual fact if you could position stuff perfectly in the drawing, that actual machining centre can't drill it in the perfect position, because it has a tolerance.
If this is a thing that you will use a lot, you could make it a part. I went through this last week with my DENSO ECU connector, and I could get the svg perfect dimensionally. But when I checked the exported gerber it wasn't perfect - the error averaged out 6/10,000 of a mm -, but that could be the conversion of units.
It was out about 6 - 1000 of a mm ADV, now it's 6 - 10,000 of a mm.

3.50012 3.50000 0.00012The node coordinates are perfect in INK now, so I assume it must be the conversion in the Gerber from inch to mm.
Old drawing had mysterious XML somewhere, so the problem is solved by making a new one.
