@Bernard you are AMAZING!! but i'm trying to put the pieces together. that link shows "an early version of unigraphics" do you mean autocad? was autocad an early version of unigraphics? Also, why was los Alamos labs producing these images? I have an original framed autocad blueprint of the image from the link. what do I have?
AutoCAD and Unigraphics (now called NX) are two different CAD packages, and neither was an early version of the other. As for your framed blueprint, does it actually say "AutoCAD" on it?
