I build a folk stringed instrument from Puerto Rico and would like to create the plans for it based on how I build it. I got TurboCad for Mac about a year ago and between one thing and the other have not come around to creating these, since when I started, it took a hell of a lot more time than I thought it would take. Any guidance or resources I can get to learn how to create these plans.
Is it possible to scan a picture of your instruments and then overlay the drawing first. Actually, I dont even have a clue where to start.

Therefore I am open to suggestions.
