What are the advantages and disadvantages of CAD/CAM ?

Advantages:

1. Can be easily erased and changed.
2. Can be zoomed in for more detailed sections.
3. Can be copied and pasted many times.
4. Depending on skill, can be neater.
5. Can be quicker.
6. Can be sent to elsewhere quickly.
7. Can be stored in a safe place.
8. Can be checked for measurements by the computer.
9. Can easily mass produce identical products.
10. Can work throughout the night so can produce product 24 hours a day

Disadvantages:

1. If computer problem, all data will be lost. 
2. If not checked properly, the object created can go very wrong.
3. Can be very expensive.
4. Can be hard to do and handling needs training.
5. Since not manual, can be slightly irritating because if not familiar with technology, it is very hard to insure exactly what is wanted by the designer e.g. If wanted something engraved instead of cut, the line color has to be changed into blue instead of red. 
6. Sometimes you can't do everything you want to because the tools aren't available.
7. Lots of people lost their jobs when CAD CAM originally came out.
