What is a physical model primarily intended for?

A physical model is primarily intended for design review because it provides a tangible representation of the design concept, allowing stakeholders to visualize and evaluate the product before moving into production. This hands-on approach enables designers, engineers, and clients to assess the scale, proportions, and overall functionality of the design in a way that digital models may not convey fully.

During design review, feedback can be gathered and potential issues can be identified early in the development process, which helps to refine the design and ensure it meets the intended specifications and user requirements. This aspect is crucial because any necessary adjustments can be made at this stage to avoid costly changes later in the production process.

Other options, such as aiding in functional testing, cost estimation, or material analysis, serve different purposes. While these aspects are important in the overall product development process, they are secondary to the primary use of a physical model in facilitating effective design reviews.
