I remember that an early version of Auto Cad came with a Constitution class sample file but the history on it escapes me. When I was studying drafting during the late 80ies the Unigraphics system we were learning about had a Constitution class sample drawing in its sample Files. I Kit bashed quite a few Franz Josephs ships and Plotted them to hard copy. only 3 copies existed One copy went to my Drafting Instuctor for his son, another went to a friend who helped me on those lunch hours and I have the third copy.
Looking at the both pictures its looks somewhat Like the Unigraphics file
Could you get an over all view of the picture
Very nice what I can see
