What role does a physical model play in the design process?

A physical model plays a vital role in the design process by allowing for testing and evaluation of a design in reality. This hands-on approach enables designers and engineers to examine how their concepts behave under real-world conditions. By creating a physical representation of a design, teams can identify potential issues, assess functionality, and iterate on their ideas based on tangible feedback.

Building a physical model facilitates experimental trials that might not be possible with digital models alone. It allows for practical insights into ergonomics, usability, and performance, which can lead to significant improvements before final production. The ability to manipulate and interact with a model often reveals insights that simulations cannot provide, making it an essential tool for both refinement and validation of concepts throughout the design process.

Other options do not capture the true utility of a physical model in the design context. For example, while a model can certainly aid in visual presentations, this is not its sole purpose or primary benefit. Describing physical models as purely costly endeavors with no practical uses or as decorative items overlooks their significant contributions to testing and refining designs effectively.
