One problem. Can't erase film. Early CAD would follow soon, so this would have a short product life.
I used to be a draftsman, early in my career, and had that classic draftsman's printing hand. Now, after using computers, for decades, my handwriting is undecipherable chicken scratching. For working drawings, using the results from a mechanical pencil was just fine. For published documents (manuals, text books, ...) the drawing was done in ink, with the aid of templates. This was a difficult skill, since ink could run under, and bleed to an adjacent surface. Also, you can't erase ink, either. When CAD hit the personal computer, things changed quickly. Printer technology lagged, and early drawings came out of pen plotters. A few specialty color dot matrix graphic printers were produced, but it took forever to draw a schematic, and the results a bit iffy, when compare to a plotter. The general concept of this video did live on. There's the Gerber photo-plotter used to make artwork, for printed circuit boards. The Gerber file is still a common, if not dominant, format used in the PCB industry.
