What is (Mechanical Engineering ) CAD software?



This description is for general people. I am starting my description with very simple example so that any person can understand about CAD softwares.
All of us know what is a rectangle and how to create it, since our school days. But see now, how easily a rectangle can be created in CAD software that is used by a CAD designers on the following
tutorial.


Simple as well as complex geometric shapes created in 2D can be converted in 3D using a CAD application. See the following most simple part creation examples:-

There are many software in this field. I have used Autodesk Inventor, SolidWorks Siemens NX and Creo Parametric my self that is why I recommend them for such work.
The models are created on computer before manufacturing, every thing is analyzed (weight, material, mass, cost etc). The models can be modified at any moment . Then the final output is manufactured by factory using CAM software.
There are CAD (Computer Aided Designing) software which witch are integrated with CAM (Computer Aided Manufacturing) software.
