ITPEC IP April 2026 Question 88
Which of the following is an appropriate explanation of CAD?
Explanation
Design and drafting with the use of computers — CAD stands for computer-aided design.
CAD software creates and edits drawings and 2D or 3D models of products and structures on a computer. Designs can be modified, reused and checked faster and more precisely than on paper, and the data can be passed on to manufacturing.
Answer (c)
Why not others:
- •(a) — education with computers is CAI (computer-assisted instruction), or e-learning
- •(b) — manufacturing with computers is CAM (computer-aided manufacturing), which often takes CAD data as its input
- •(d) — computer support for software design, development and maintenance is CASE (computer-aided software engineering)
Key rule: CAD designs, CAM manufactures, CAE analyses and simulates, CASE supports software engineering, CAI teaches.
