Custom hole cutting for mosfets?

[diptracy]

Hi, I've been using diptrace for a little while and really like it but im starting to do more tricky things. I would like to know how you do custom routing (milling) of a hole (like in the example below). The manufacturer has made a hole for a rf mosfet and they've made little inserts which cutout inside. The parts that cutout, fit onto the ends of a pignose ferrite and make a 9 to 1 transformer which goes onto the pcb just to the left of the mosfet hole. There is an example of this infront of the pcb.

I need to do the same, is it possible to do with diptrace?

Draw the required slot(s)/cutout(s) on the Board Cutout layer. Here is an example of how one PCB manufacturer would like to see slots/cutouts defined - https://www.eurocircuits.com/blog/slots-and-cut-outs/. Other board houses might have different requirements.

Thanks, I managed it, hopefully pcb house will be ok with it
