Which term refers to a visualization of an idea, often created on paper or through software, in two or three dimensions?

• A. Mock-ups
• B. Graphical models
• C. Motion capture
• D. Part drawings

Answer: (B)

Visualizing an idea in two or three dimensions using paper sketches or digital tools is described by graphical models. This approach presents the idea’s form and relationships in a simplified visual form, enough to explore concepts and communicate them without building a full prototype. It’s flexible for quickly testing shapes, layouts, and overall structure. A mock-up tends to be a more developed, sometimes tangible representation aimed at approximating the final look or function; part drawings are precise technical drawings of individual components; motion capture records movement rather than creating static visualizations. Because the description centers on a dimensional visual representation created on paper or with software, graphical models fit best.
