3D modeling has fundamentally transformed product design by allowing for visualization and simulation of concepts in a detailed and interactive manner. Designers can create three-dimensional representations, providing a clearer understanding of proportions and functionality before actual production. This facilitates collaboration, as stakeholders can visualize and give feedback on designs early in the process. Furthermore, 3D modeling enables rapid prototyping, reducing the time and cost associated with physical models while enhancing innovation, creativity, and the ability to refine products more effectively.
