. CAD stands for Computer Aided Design.
. It is software used by engineers, architects and other professionals to create drawings or technical illustrations.
. Can create 2D and 3D drawings.
. Can be used to design products like electronic boards etc.
. CAD drawings will be formed from polygons, lines, circles, curves, text etc.
. We can edit individual elements that make image.

Different CAD programs:
. There are many programs to design drawings in 3D and 2D models. Few of them are:
- AutoCAD
- IntelliCAD
- SketchPro
- Scan2CAD
- CorelCAD
. We can also use online editors to create 2D 3D drawings.
CAD File Formats:
. We can save the drawings designed in various formats.
DWG:
. Stands for AutoCAD DraWinG database file.
. It is native file format in AutoCAD.
. It handles 3D geometry.
. Stores information like colors, line weights, x-references.
. Encodes information in 0's and 1's
. It is not supported by all other softwares expect AutoCAD.
. It can be converted into PDF to share the files but receiver could not edit the individual elements.

DXF:
. Stands for Drawing Exchange Format File.
. DXF is open source used by almost all CAD softwares.
. It uses plain text or ASCII format.
. It is of larger size since every information is spelled in text and numerals.
. It supports only 2D lines, text, polygons and circles.
. DXF is used when we want to share drawings between different CAD or vector based programs.

Opening CAD files:
. We cannot open and view any CAD files directly.
