In a CAD workstation, which of the following is NOT an input control method (i.e., not used to provide user input to the system)?

Introduction / Context:
Computer-Aided Design (CAD) systems support multiple devices for precise user input, such as selecting entities, entering coordinates, and invoking commands. Distinguishing input devices from output peripherals is essential for configuring an effective CAD setup.

Given Data / Assumptions:

• Input control devices are used to navigate, select, or command.
• Common CAD inputs: mice, joysticks/space mice, function boxes, touch interfaces.
• Output peripherals render drawings or models to paper or other media.

Concept / Approach:
A plotter is a hardcopy output device that draws vector graphics on paper or film. It does not provide user control input to the CAD application. In contrast, a joystick/space mouse manipulates view orientation; a programmable function box provides shortcut keys; and a touch terminal accepts direct touch input.

Step-by-Step Solution:
1) Classify each option as input or output. 2) Recognize that plotters generate physical output, not input signals. 3) Confirm the others are user input mechanisms. 4) Select “Plotter.”

Verification / Alternative check:
CAD hardware guides list plotters/printers under output devices and joysticks/function boxes/touchscreens under input devices.

Why Other Options Are Wrong:
Joystick: navigational input. Programmable function box: command input. Touch terminal: direct input. “None” is invalid since plotter is clearly output.

Common Pitfalls:
Confusing “control” with “controller” hardware; here “control method” simply means a way the user provides input to CAD.

Final Answer:
Plotter
