Ruth,
 
Well, we old farts have our doubts about these little squirt CADD [computer-aided drafting and design] jockeys' ability to do anything but play with the computer, which is to say that WE are the only ones who really know how to be real architects and really design useful things that we understand and work well and are beautiful and all that shit.     That's why we use the snotnoses to draw up stuff on the computer, like the auto engineers.
 
The new photogrammetry uses some sort of laser-shot system, which acts like a radar to record the distance from wherever their machine is set to the 10 zillion points in space that represent the front of a building, with all it's nailholes and mullions.  The photogrammetry geeks feed all that data into a computer that plots these 10 zillion points and gives you a drawing.
 
IMHO, the process of personally measuring up and drawing a building by hand gives one a great deal of information about it that one wouldn't get by just looking at a finished CADD plot (drawing) of the same thing.
