Making cut outs in PCB

Hi,

I don’t know if anyone can help me with this - it’s been driving me nuts for a few days now, and similar to Andy’s donut problem.

When importing this svg, I get the no cutouts detected message. Here’s roughly what it should look like…

…I’ve tried everything in this thread, plus this…both several times. I’m honestly just considering a drill and a hacksaw at this stage!

If anyone can see what’s wrong with the xml, it’d be much appreciated.

Cheers

Rich
