In CAD/CAM, which feature stores part design information?

• A. The database
• B. The gage line
• C. CAM
• D. DXF

Answer: (A)

In CAD/CAM, the central repository for part design information is the database. It stores the model geometry, feature history, constraints and dimensions, material properties, tolerances, and revision history, providing a single source of truth that can be accessed by both design and manufacturing processes. A format like DXF can carry geometry for transfer or viewing, but it doesn’t preserve full design intent, relationships, or history. The gage line relates to measurement, not storage, and CAM uses the CAD data to generate toolpaths, not to store the design itself. So the database is the best place to keep all part design information.
