What is the function of the "shell" feature in graphic communications?

The function of the "shell" feature in graphic communications is designed to create a hollow model by removing the interior material from a shape. This is particularly useful in 3D modeling and design, where creating a lightweight structure without compromising the exterior form and details is often necessary. The shell feature allows designers to specify the thickness of the walls of the object, enabling the creation of functional components that maintain structural integrity while being less material-intensive.

This capability is vital for a range of applications, including product design, architectural modeling, and prototyping, where internal space is required—such as for the addition of internal components or for weight reduction. By utilizing the shell feature, designers can effectively communicate the desired properties of an object, enhancing both aesthetics and functionality.
