I started doing this when i was building a Goldberg Cub and a friend had crashed his and needed a template for a new firewall. I made a template from mine for him, and made templates for all of the other parts while I was at it.

I didn't make actual templates, I just traced all of the parts onto a few sheets of paper. Then, later I realized that by saving the frames, I already HAD all the templates I needed right there.
