What advantage does CAD provide over traditional paper and pencil design?

• A. CAD designs are easily modified and reproducible.
• B. CAD is slower to produce than paper drawings.
• C. CAD maintains only 2D views.
• D. CAD cannot be reused for production.

Answer: (C)

The main advantage of CAD over traditional paper and pencil drafting is that designs exist as digital files that are easily modified and reproduced with high consistency. When you change a dimension, add or remove features, or adjust tolerances, the digital model updates and all related views or drawings can be refreshed automatically. This speeds iteration, reduces manual errors, and makes it simple to reuse parts or entire designs in new projects. CAD also supports 3D modeling, assemblies, and automated production drawings, which further streamlines design-to-manufacture workflows.
