Computer Aided Design (CAD)

Advantages And Disadvantages Of Computer Aided Design (CAD) Over Manual Drafting

Sample CAD drafting work
The advantages of CAD include: the ability to producing very accurate designs; drawings can be created in 2D or 3D and rotated; other computer programmes can be linked to the design software. With manual drafting, you must determine the scale of a view before you start drawing. This scale compares the size of the actual object to the size of the model drawn on paper. With CAD, you first decide what units of measurement you will use, and then draw your model at 1:1 scale.
