AutoCADThe Word AutoCAD is made up of two

words “Auto(logo of company)”and CAD “(computer aided design)”.

It is widely used in industry for 2D drawing and 3D modeling.

It is developed by Autodesk company.In another way we can say that AutoCAD

is a designing course , which is performed by the help of computer.

AutoCAD software was firstly launched by Autodesk company in Dec. 1982.

It comes in India in 1988.The first version of AutoCAD was R1 after

that R2,R3,R4…………… and so on.Latest version is easy to use and over

come the difficulties of old version.

Some 3D Modeling

Use of EXTRUDE Command If you “Extrude” a surface into the third

dimension, you simply add a thickness in section. This basically is same as creating a “solid” object .
