Concepts. A 3D model can help express an idea in conceptual stage (since an image is worth a thousand words).
Practical applications: Illustrate new ideas and concepts, pitch project ideas to teams or leads.
Structural Design. A rough sketch allows an idea to take shape. But it is the wire-framing that ensures the structure will work. The 3D tool connects graphic design and effective packaging design.
Practical Applications: Structural package design, bottles and boxes.
