how to draw a circle video

I usually drive in a double edge pin right into that spot, when I have to do a lot of them. They all turn out Red for some reason, and very soggy. :)
 
that is why I own a complete set of drafting compasses, easy circles...
 
lol, red and soggy, I thought that this would be handy for someone making really quick layouts for models, pre-compass and finalization.
 
It is a neat idea, hard to repeat, for multiple circle, in size, but I have used that method, and it does work.
