What are the advantages and disadvantages of cad?

Answer 1

Advantages:

Can be easily erased and changed

Can be zoomed in for more detailed sections

Can be copied and pasted many times

Depending on skill, can be neater

Can be quicker

Can be sent to elsewhere quickly

Can be stored in a safe place

Can be checked for measurements by the computer

Can easily mass produce identical products

Can work throughout the night so can produce product 24 hours a day

Disadvantages:

If computer problem, all data will be lost

If not checked properly, the object created can go very wrong

Can be very expensive

Can be hard to do and handling needs training

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 colour has to be changed into blue instead of red.

Sometimes you can't do everything you want to because the tools aren't available

Lots of people lost their jobs when CAD CAM originally came out
