Computer-Aided Design (CAD) | Advantages, Co‐ordinate systems, drawing commands of CAD

Write short notes on:

  • Advantages of Computer-Aided Design (CAD)
  • Co‐ordinate systems used in CAD
  • Four drawing commands
  • Four edit commands
  • Solid modeling
  • Give the list of software, currently available for 2D solid modeling.

Answer:

(a) Advantages of CAD: The CAD system should be used in modern Engineering practices because of the following reasons :

  1. CAD systems are “User‐friendly”: Any person who has the basic knowledge of the CAD systems will be able to understand them very easily.
  2.  Better quality designs: The chances of mistakes are very less as compared to the traditional method of drawing; because the computer works very accurately, thus leading to a better quality design.
  3. Improved productivity: CAD improves the productivity of design and quality of the technical drawing as compared to the traditional methods of drawings.
  4. Reproducibility: As the drawings are stored in a database, which is a collection of data of all types related to the drawing consuming very little space. Therefore, it can be reproduced very easily in the future whenever required.
  5. Faster speed of work: The drawing can be made at a much faster speed than in the traditional method, with the help of CAD systems.
  6. Easy modifications: As a drawing can be saved many times, the changes in the drawing can be made very easily. Therefore repetitions can easily be made, which was not possible in a traditional method of drawing.
