The main difference between 2D and 3D is the fact that 2D uses flat layouts to show your product/project, whereas 3D gives the viewer a full-on idea of what the end result will be like.
We get asked this a lot! What's the difference between 2D and 3D modelling?
Although these two forms of modelling are very similar and serve the same purpose, they have some significant differences, pros, and cons in comparison to one another and are used for different reasons.
2D modelling has been the primary form of product or idea display up until fairly recently. This form of modelling uses CAD software or old-school paper and pencil to create a 2D model/design of a product or project.
Of course, 2D modelling creates drawings or blueprints in a 2-dimensional form. This means that there is no concept of depth. They are flat layouts or plans for your idea that will look similar to that of a cartoon on TV: two dimensional, leaving you to imagine what the end result will be. 2D drawings are required, for example, for the registration of design rights on a product.
3D modelling takes 2D modelling and elevates it. 3D modelling takes the product plan or design and puts it in a 3D format, often using CAD software. The end result is a visual representation of what the final result will look like when it is created. You will be able to see the product from all angles, move it around, get a real idea of what is to come.
In 2D modelling, you are left to use your imagination to visualize what the end result of a product design would be. This is why 3D modelling is taking off within the product design field.
3D modelling is something anyone creating a product idea should do regardless of whether or not they end up pitching their idea to a company or investor. 3D modelling will show you what your product is going to look like in real life. It will give you dimensions and a clear visual representation for you and investors. It leaves very little up to the imagination, which is ideal for anyone pitching a new product idea. Finishes, logos, colours and any design detail can be communicated using 3D models and animations can also be created.
