State of Art old lines drawings.

I once did the hull lines from a hundred years old drawings. I had to refresh how to recalculate the coordinates of feet’s – inches -eighths and manually input offset table. There were no original drawings. There were only pictures of them. Once again, I was amazed by the quality of the old drawings. When smoothing the lines of the hull, the surface went to the original points easily. And, in the end, I made well faired hull for production.
