DD8 is an amazing artist and has been helping my robotics team this year with designing. I am amazed at how well she can free-hand draw her ideas and would like to get her started on CAD I've seen a CAD for kids and was wondering if others have tried it and what you think. In particular, is it "too watered down" for a kid who can visualize things in 3-d, unroll them to 2-d to draw them onto a paper which she then cuts out and "rolls" back into 3-d.
