Steven,

Thank you so much for your post. Yesterday I was trying to teach this principle to some of my students, but I don't think I was getting through to them. I feel it is one of the more difficult concepts to teach. Your last post gave me some very good ideas on how to explain the Sight Size method to them. I've heard of marking a model's position with tape, but never the artist. What a good little trick. Thank you so much for all your good advice.
