I have an amazing idea for a new product, as far as I know it has never been done before, I certainly haven't seen one anywhere. My only problem is I don't know how to make up a prototype. I have an idea that may work for making a few of the components but some of the others I'm having trouble thinking up ways to accomplish this. I have no experience with CAD and although I would love to learn I don't want someone stealing my idea before I can make it a reality. Any idea on a way to make this vision come to life?
