Moment of Inspiration 3D (also known as MoI) is one example of the new generation of low cost product design CAD software solutions (alongside Blender and 3D Coat), and was the first of this new generation of tools to reach the market. Its flexibility of use is compared by many to that of other tools like Rhino CAD, but it costs less than most other kinds of product design CAD.
Its other advantages are that it has been designed to work in a way which is pen tablet friendly, and it is also one of the few low cost CAD solutions which already has a user base involved in jewellery manufacturing. This can make it an appealing entry point for prospective CAD users looking to get started.
You can also find more MoI Videos on the resources section of the MoI website. There are quite a lot of user-created videos now.
