Art design is the biggest characteristic of individual creativity, art need to createinstead of imitating and copying. In the process of production, creative thinking is the key to a successful art products, grasp the technology canproduce the same design and the product, but the hand of art and technology perfect combination is possible to create the art products. For designand production activities in the basic technical indexes and basic operation can understand and grasp the designer is unable to turn the designinto product, higher vocational art and design. This paper integrates the state-of-the-art angles and perspectives on the issues that hold specialmeaning.展开更多
