By typing in the information they want, they get the choices to choose from. Imagine in your map whether it is an architectural drawing or the exploded view of a mechanical assembly being able to add additional important information to it. The same type of information could also be used in a mechanical schematic, as well as part numbers and other pertinent information. As it stands now, when you want to do a search for a certain part number that was used in an assembly, you need to either go through your paper files or search each drawing file. On average, most cities and counties that do not have GIS in place take over 30 minutes just to locate one drawing.
Architectural firms have about the same search time.
How many drawings do you or someone in your office look for in a week. Maybe it is by location, or size, or date, or function. No longer would you need to go through stacks of drawings of buildings built in Broward County to try to find one that is 2000 square foot. Nor would you have to find the drawing of a boat that is 24 foot long that was designed in 1980. You could now type in the information and up it comes.
