Within the CAD/CAM domain, which item best represents a Computer-Aided Manufacturing (CAM) technology rather than a design-only artifact?

Introduction / Context:
CAD (Computer-Aided Design) tools emphasize creating and refining models and drawings, while CAM (Computer-Aided Manufacturing) tools translate those models into machine instructions and coordinate production equipment. Distinguishing between these helps clarify toolchains in product development.

Given Data / Assumptions:

• Design activities include drafting and geometric modeling.
• Manufacturing activities include toolpath generation and machine control.
• Documentation supports both but is not itself manufacturing control.

Concept / Approach:
Numerical control (NC/CNC) is the essence of CAM: programs (G/M codes or higher-level toolpaths) direct machine tools (mills, lathes, cutters) to fabricate parts. Drafting and geometric modeling remain on the design side, creating the digital definition but not executing fabrication.

Step-by-Step Solution:
1) Separate design deliverables (drawings, models) from manufacturing directives. 2) Identify the option that instructs machines: numerical control. 3) Exclude drafting/documentation/modeling as they do not drive machines directly. 4) Choose 'Numerical control' as CAM.

Verification / Alternative check:
CAM suites output NC toolpaths; CNC controllers execute them to cut material, confirming the classification.

Why Other Options Are Wrong:
Option B/D: Core CAD activities.
Option C: Documentation accompanies processes but is not a manufacturing control technology.
Option E: Not applicable since a CAM technology is present.

Common Pitfalls:
Confusing CAD file formats (e.g., STEP) with the machine-specific NC programs that CAM generates.

Final Answer:
Numerical control
