Engineering (drawings, illustrations), oh sure, when I was a boy I drafted for a company that was a vendor for the city, all sorts of engineering prints, by hand - soon after, a specialized software was in effect (don't remember the name, but proprietary anyway), then again soon after that AutoCAD came out for a near $4,000+ for the program, then soon after that, another new program now used, and if not a new program an expensive update. What I'm getting at everything changes and we are stuck either updating or losing out.
Of course in a pinch, you can always ask the government for a copy of your pictures.
