Answer:
it doesnt work very well and CAD is better also its better to use your hands
how can CAD be better? CAD and CAM are nearly the same thing.
Cad is not the same as CAM. CAM is usually for product design, while CAD is for general purpose. If you want to know more, I suggest that you hire a freelancer at Freelancer.com. Besides helping you, they can also do any kind of project for you. Use this code "3DPROTOTYPE" as reference. Thanks

Actually you have those answers backwards. CAD is a design program that allows you to do the actual design work of a new part or the modification of an older part. Once you have completed the design of the part and depending on the CAD program you are using you can generate blueprints or a 3D solid model of the part.
Once you have the design completed the part file is imported into the CAM program. Here the user generates the tool path (the path the cutting tool will travel to remove metal, plastic or whatever) decides what tools are going to be used.
