Computer aided design or CAD involves using computers to help with engineering and design for a wide range of projects in various industries. It has been important in applied computer science for decades.

CAD describes using computers to create technical drawings, whereas AutoCAD is a specific type of professional CAD software that can create both 2D and 3D drawings and models.

9 Types of CAD Software:-

• SolidWorks
• Inventor
• Revit
• AutoCAD
• Civil 3D
• MicroStation
• CATIA
• Creo

Computer-aided design (CAD) software today exists for all the major computer platforms. For example, they exist for Mac OS X, Unix, Windows, and Linux.

2D CAD is a two-dimensional Computer-Aided Design, 3D CAD is a three-dimensional Computer-Aided Design. 2D is a display of length and height on a plane without depth while 3D is defined as 3-dimensional drawings or models they described objects with height, width and depth.

• Saves Time
• Improves Accuracy
• Decreases Errors
• Better Quality
• Ease of Understanding
• Quick Sharing for Collaboration

For small and medium sized manufacturers who develop products, it is as straightforward as that. Likewise for supply chain manufacturers who principally are production based, but want to increase their flexibility and ability to handle customers’ CAD data, the ability to understand CAD files and organise their production set-up accordingly is paramount.

In short they reduced development lead-times, fewer errors, significantly better quality and finally, big resultant cost reductions.

Some of the best CAD software are:-

• Open Cascade
• Freecad
• Bricscad
• Leocad
• Autocad
• and many more..
