Not long time back building designs & drawings was a pain in the neck by the hand using the conventional pen and paper on a drafting table.
This soon changed with the advent of the desktop computer, which gave rise to Computer Aided Design (CAD). For more information you can check this URL : http://www.bluentcad.com. Changes can be made in a jiffy without having to redo the whole drawing, which was earlier a tiresome process.
Now with CAD in picture, which is known as Computer-aided design, you need not fear about many of your drawings that are lost or destroyed, there is a booming service industry, which is at your doorstep to create computerized CAD drawings & designs in 2 Dimension & 3 Dimension of existing buildings.
