Large format plotters are common place in oil & gas companies. No other industry builds projects as large, complex, and expensive as oil & gas and plotters are the most effective solution anyone has found for being able to visualize the massive scale of things (short of a few cool VR nick-nacks that sit empty). I don't think they're such a bad option either. Until someone starts manufacturing "retina" displays at 4 ft. tall by 10 ft. long everything else is a waste of time.
