Heres my 2 cents on that one... Hand drafting is great, it looks nice when well done, and a well drafted plate with nice line weights truly looks like a piece of art. That being said, hand drafting as a communication tool does not work well in today as it did 15 years ago. The time saved by using a drafting program, especially for lighting, is no contest. For scene design I feel the same way, any TD worth their salt will take any hand drafted plates and put them into autoCAD, if the scene designer puts them their first they save time on all ends. As an M.E. I can deal with hand drafted plots, but I much prefer digital. You can make changes quicker, get the info that you want faster, and produce hang cards and pipe tapes much faster. Also, I hate carting around D size plots. Hand drafting does give the same information, but the exactness of CAD programs has gone way beyond what hand drafting can do.
