so i figured out how to convert 2d coordinates into 3d and back. does anyone know of a program that can let a person draw something, then convert it to a 3d model? if no one knows then i want to make that program. it would let a person draw a picture using lines and triangles then convert the points into 3d coordinates that would become a model. i think it would be really sick. a program MUST already exist, does anyone know?

I once found this kind of program, but unfortunately I can't remember it's name. I know it was insanely expensive though.
