Which type of object can accommodate the addition of a rib feature?

• A. Sheet Metal Part
• B. Solid Body
• C. Wireframe Model
• D. Surface Model

Answer: (B)

The addition of a rib feature is primarily associated with solid bodies because ribs are generally used to provide support or strengthen a wall of a solid object without significantly adding weight or volume. In the context of solid modeling, a rib can be defined as a thin, supporting structure that is typically added to reinforce an existing feature or to define a more complex geometry. When you create a rib in a solid model, you are essentially taking a face or edge of the solid and extending it into a different plane or direction to create this support feature. Solid bodies are specifically designed to hold and manipulate 3D volume and mass, making them ideal for applying rib features that enhance design integrity and performance. On the other hand, sheet metal parts, while they can incorporate features like flanges or bends, are not typically associated with rib features in the same sense as solid bodies. A wireframe model, being primarily a collection of edges and vertices, lacks the volume necessary for ribs. Similarly, surface models are defined by surface boundaries rather than volume, so the concept of adding a rib doesn’t apply as it would in solid modeling. Hence, solid bodies are fundamentally suited for accommodating rib features.
