How are you using Margin Layer?

Hi all, how are you using Margin layer in your PCB layouts?

I am interested the different ideas how other designers implement Margin layer in their layouts, be it hobby design or commercial designs at work.

Well I have used an arc on the margin layer to remove ground plane fill for a screw notch on an m.2 board. Without the margin arc it has a solid fill:

Then just a little arc on margin layer:

I use Margin layer for an Aid in placing Parts so they Keep-Out of the CNC Milling Bit… Also use them for Comments if not using other User layers and Comment layer…

Example shown is from one of my custom New-Project Templates… (FYI-the White rectangles are PCB Hold-Down’s to hold it in place when Milling…)
