Question

The basic benefits of CAD systems include
1. Increase design productivity
2. Creation of manufacturing data base
3. Improved communication and documentation
4. All the above

Answer 1

Correct Answer - Option 4 : All the above

Explanation:

AutoCAD has various advantages and reasons for implementation. Some of the reason are discussed below:

• To improve communication through documentation:
  • The use of CAD system provides better engineering drawing, more standardization in the drawing, better documentation of the design, fewer drawing errors and greater legibility for the drawing.
• To increase the productivity of the designer:
  • CAD helps the designer to visualise the product and its component subassemblies and parts.
  • This reduces the time required to synthesize, analyze and document the design.
  • This productivity improves the results not only into lower design cost but also into shorter design project completion time.
• To improve the quality of the design:
  • A CAD system permits thorough engineering within a short time using various software and a large number of design alternatives can be investigated.
  • Design errors are also reduced by the accuracy built into the system by means of calculations and check available within the system.
  • These factors lead to an improvement in quality and accuracy in the design.
• To create a database for manufacturing:
  • In the process of creating the documentation for the product design, much of the required database to manufacture is also created which can be applied for several computer integrated manufacturing (CIM) applications like CNC programming, programming of robots, process planning and so on.
