The difference between 2-D and 3-D design is that 2-D is flat and has only two dimensions, while a 3-D design allows for depth and rotation. 3D product design is the creation of a product in a virtual environment such the product has three dimensions (height, width, depth). The result is a digital prototype of your product, one you can explore in detail. Without digital prototyping, you’d need to use more budget-vaporizing physical prototypes, watch time slip away, and get to market later with a product that might not be optimized. In general, these terms define the difference between a painting and a sculpture. Most of these shape designs are used in geometry 3D design makes your life as a product designer easier and faster, giving you more time and energy to devote to optimizing your product.
Designers usually take one of two approaches to 3D design and solid modeling: direct or parametric modeling. Direct modeling means you can push and pull directly on geometry. Use it for speed and quick changes. Parametric modeling means that the software maintains consistent relationships between components, so a change to one component is a change to all.
