I have a school project coming up where you have to invent something, make a model of it, and draw a 2D and 3D drawing of it from all sides. Being the terrible artist that I am, I am looking for a better way to do it. Is there some sort of software that can take a picture( like one I take from a camera and upload to the computer) and outline the general shape. I dont believe the drawings have to be in color so thats not an issue. Just a black outline of the figure would be great.
