1. What are the Merits and demerits of CAD?

Merits of CAD

1. Saves time: When you are using the computer-aided design software, it will

save your time and you can make better and more efficient designs in shorter

time duration.

2. Easy to edit: When you are making designs, you may find the need to make

alterations. When you are using computer-aided design software, it will be

much easier to make any changes because you can fix the errors and modify

the drawings easily.

3. Decrease in error percentage: As the CAD software makes use of some of

the best tools, the percentage of error that occurred because of manual

designing is significantly reduced.

4. Decrease design effort: When it comes to the amount of effort that was

needed for the sake of designing the different models, it has been reduced

significantly because the software automates most of the task.

5. Code re-use: As the entire task is carried out with the help of computer tools,

it removes the problem of duplication of labor, you can copy the different

parts of code and design which can then be reused multiple times over and

over again.
