BLUEPRINTS AND COPY MACHINES

Drawings on tracing papers (on vellum or transbonds) are considered to be the original copies.  And after finishing all the drawings be it done manually or by CAD, one usually need a number of copies of these drawings.  CAD drawings though need to be printed usually on large printing machines, some designers want them blue printed.  They like the white or bluelines that go with the copies instead of just the black lines on computer printing machines.

Blueprints basically are just a reproduction of the original drawings.  Right here, blueprints are still used and honored for legal purposes and for construction.  Even students of Architecture also tend to blueprint their projects as always required by some of their instructors.

There is this sense of accomplishment when a group of draftsmen were off to have their drawings blueprinted.  The print's aroma stink of ammonia, they usually are lighten up upon waiting for the prints to be done.  There is the sense of pride of having another project done highlighted by the blue prints.

Usually they are off for the building permits after the prints are done.  Copies of these blueprints had to handed out to building officials for approval.  And they'll have to wait until it's time to build.
