CAD, or Computer Aided Design and Drawing (CADD), is a design and technical documentation technology, which uses automated processes instead of manual drawing. If you are a designer, draftsman, architect or engineer, you may have used 2D or 3D CAD programs, such as AutoCAD or AutoCAD LT software. These widely used software programs can help you draw construction documents, explore design creativity, display design concepts intuitively through realistic rendering, and simulate the design effect in real environment.
