Sorry if I came out as uptight, but the next time someone demands an explanation of how I do my drawings I will simply reply "With my hand."
Seriously, at least explain why are you asking that. And be more nice! Like..."Hey,sorry to bother you, but I'm not sure your deviation belongs to the folder where you submitted it. Can you tell me what sort of tools/software you used for that?
Thanks,it will be of great help!"
