CAD is making our jobs done in a really fast way. You can draw a project for example in couple of hours instead of hand drawing (which will took you nearly a week maybe). We cannot say "there are many disadvantages of CAD". But maybe a few can be listed here;
- Fully automated solutions may have mistakes those you may not recognize.
- A computer doesn't have the vision or experience of a human. So if there is something that needs to be cleared, machine may decide wrong. Your vision or experience will guide you to a better solution than the machine does.
- Using machine for everything will make you think less then you should. You may not be able to improve your mind, your thinking style to solve something. Machine will do that for you.
These can be the disadvantages...
