Examples of cad

CAD stands for Computer Aided Design. There are multiple categories of CAD systems:

1. 2D CAD - a typical example is AutoCAD

2. 3D CAD - a typical example is SolidWorks

The classification of CAD systems can go into vertical specialization

1. Mechanical mainstream CAD - i.e. SolidWorks, Autodesk Inventor, SolidEdge

2. Electrical CAD - i.e. Cadence, Mentor

3. AEC - SketchUp, various Autodesk packages

In addition to that, there is a special class of highly specialized design systems that can be considered as CAD as well:

1. CATIA (from Dassault System)

2. NX (from Siemens PLM)

3. Creo-Parametric (former Pro-E, from PTC)

Also, there are lots of specialized systems that embed CAD functionality to provide 2D and 3D graphic.
