CAD

What is CAD?? CAD is Computer Aided Design .I ever learn little bit about AutoCAD when I study in technic school. I also learn CAD this time (AutoCAD subject). I learn how to use AutoCAD want to do two dimension(2D) and three dimension(3D) drawing.When we want to design something use computer, we use this software. CAD is used to design buildings and items. A popular CAD program is AutoCAD. CAD systems are high-speed workstations or desktop computers with CAD software. A graphics tablet is used for drawing, and a scanner may be attached for additional input. The output of a CAD system is either printed or electronically transmitted to a CAM system, which builds the objects. CAD software is available for generic design or specialized uses, such as architectural, electrical and mechanical. CAD software may also be highly specialized for creating products such as printed circuits and integrated circuits.
