Tracing holes

Hi Everyone. I am a real novice and still finding my way around this ingenious machine.
I am anxious to male use of the tracing tool and I have managed to make reasonably good traces of the shapes, however, placing the holes in the right spot and right diameter is an absolute mess… No clue how to proceed…
Any help is appreciated, and hope there is a video out there, as I am not good with the phraseology used with this machine…
Thanks everyone!
