This is a very basic question. There is an armoured car i would like to make a card model of but none exists. I have a good, to scale, 3-view of it. Is there some way of designing a card model from this threeview, without using a computer (ie by hand)? I realize i will be missing the back on the card model i design but that will be easy to fill in once i get the basic shape of the sides, front and top. It seems to me that there should be a way, since it is all angled, flat surfaces but it's tricky because some of the surfaces are angled across the views and so don't appear true in any of the 3 views. I can just trial and error it but i was hoping to find something a little more precise. thanks for any help.
