3D modeling contributes to product design by allowing designers to create detailed and accurate virtual representations of products. This facilitates better visualization of design concepts and enables designers to assess and modify aspects like dimensions, materials, and structural integrity before the manufacturing phase. Moreover, 3D models can be easily shared for collaboration and feedback among stakeholders. This process significantly reduces development costs and timeframes, enhances innovation, and minimizes errors in production by ensuring everyone has a clear understanding of the design.
