Which term describes the use of computer systems to aid in the creation, modification, analysis, or optimization of a design?

• A. Digital Audio Workstation (D.A.W.)
• B. Computer-aided design (CAD)
• C. MIDI Show Control (MSC) protocol
• D. LEDs

Answer: (B)

Computer-aided design is the use of computer systems to assist in the creation, modification, analysis, or optimization of a design. In theatre practice, it means building precise digital models of sets, lighting, and other design elements, making changes quickly, checking how components fit together, and refining the design to meet constraints like cost and performance. This holistic Design-with-a-computer approach is what CAD embodies, going beyond just drafting or listing components. A digital audio workstation focuses on recording and editing sound, MIDI Show Control is a protocol for device communication during a performance, and LEDs are lighting components, not a design process.
